This may not be the place to ask..but im going to anyway. I was searching through the internet to figure out what kind of rash my baby has. This is how I came upon your site. The rash that your son had looks exactly like my sons. I was wondering if you had to get any medical treatment for his heat rash, and how long it lasted. My son has had this rash for several weeks, which it barely clears up and comes back. my Son doesnt seemed to be bothered by it. It flares up when he lays against anything (like my shirt) and will lighten after laying without clothes on for a while. sound familiar? Danyelle Sunday, September 3rd, 2006 at 20:32:44 Your son may have Fifth's disease (Erythema Infectiosum)It will fade and then come back during periods of emotional stress (crying) or when the child gets warm or is out in the sun. For most this is very benign and causes little problems. Generally it starts with a slapped cheek appearance of the cheeks. Followed by the rash. Sometimes there is slight fever and a feeling of malaise. anna Wednesday, September 6th, 2006 at 19:21:51 Dear Danyelle, Did you ever find out what your son's condition was? My son has the same thing just on his chest area though. I took him to doctors and she wasn't sure either. He had it for about a week and it was gone for about a week and it flared up again. He doesn't seem to be bothered by it, but i am. What to do? Janice Friday, October 20th, 2006 at 15:03:50 Hi my name is Chelsea. im allergic to temperature change, mainly heat. ive had it my whole life. i break out in hives when my body raises in temperature.. whether its due to exercise, spicy foods, or just laying out in the sun. its completly harmless yet very itchy. and i have to say in high school i was quite embarressed, i break out in hives ALL over my body, sometimes even the roof of my mouth or even my eyes itch. i havent been to alot of drs about it because they all have told me the same thing, take benadryl. but really..its not worth it. by the time i sit down and cool off..the allergic reaction is gone. i hope im of help to yall. i have never met someone with the same allergic reaction as me, yet similiar, i once met a boy who was allergic to cold. i replyed to your bulletin because your sons hives look very much soo like mine do. if it helps any i was told by a dr years ago that its very common for babies to be allergic to heat yet it may fade wwith age, unfortunatly mine didnt, im 19. but theres hope. Chelsea Friday, November 3rd, 2006 at 21:45:19 It is impossible to diagnose something over the internet. This could be as simple as 'contact dermatitis' due to a soap or detergent. Cocamide DEA is a commonly used element in shampoo and liquid soap. I am allergic to it and goat a rash from a body wash I used. See an allergist, that's my recommendation. Allergies untreated can get worse, histamine reactions gets more severe over time as the body tries to compensate. I know a great allergist, Dr. Arthur Biedermann, Allergy Associates. Kevin Thursday, December 28th, 2006 at 03:55:26 HI I have this rash and I am not sure if it is a heat rash. It is everywhere on my stomach, upper legs, back, amrs, hands, and other places. I have no idea what it is it looks very much like your son's rash. I am 14 years old and I am worried. It could be an allergic reaction but i haven't put my finger on it yet. And the worst part is i am in crutches. I hyperextended my leg. (bent it the wrong way) Lauren Monday, March 5th, 2007 at 13:02:32 hi my names julie and i have a rash just like your sons which i think i got from being out in the sun all day, because that morning I woke up i didnt have any rash but when i got home from the beach i had all these white bumps on my forehead which changed into red and itchy andd i was wondering if thats heat rash? and what you used to cure it. jules Sunday, July 29th, 2007 at 13:23:55 Hello, I have exactly the same as Chelsea. It is started when I was about 22-23. That time it was not bad. Only extreme overheating would cause the redness. No itching. After that it was getting worse. Now I am 30. I get red and itchy skin in 1 minute of exercising. And then I have to cool down for 20-30 minutes before it will go away. The doctors I visited were useless. I tried several antihistamine medications. The one that helped with itching only is cetirizin (for example Zytrec). Also I found that if I exercise every day, then I get less and less of the problem every day. But if I stop for a day or two it all comes back. Here is the article that might help a little bit http://yourtotalhealth.ivillage.com/sun-heat-allergies.html Good luck and health to all. Paul Monday, March 17th, 2008 at 08:22:23 Everyone who has this persistent rash should get checked for food allergies. My daughter has had eczema and rashes sporadically for 7 years, and it turns out she is probably gluten-intolerant (and can't have wheat, etc.). Lauretta Friday, April 4th, 2008 at 18:19:12 My daughter is a month old and has this same rash... the dr. said it is an allergy to the detergent and sais use dreft, but dreft is expensive and we are already using a free and clear detergent. Besides, in the case of my daughter it is mostly on her face and neck and chest, all places where she contacts my skin. If it was from her clothes she would have it everywhere her clothes tough. I am thinking it is an allergy to my body wash, I am going to try and switch to a differnt one. Jill Tuesday, May 6th, 2008 at 15:45:18 I have the same rash as Chelsea, I went to a few Drs and yet no one was able to diagnose what it is. I usually get the rashes in the summer or when my temperature rises. I tried cortisone and that seems to help, but to tell you the truth, a cold shower or dip in the pool works better. I guess is common, but it does a number on your self steam. I had it since I was 17-18 and now I am 34. The only thing that bothers me is when I am out in public. The other day, I went to a physical therapist, and she would not touch me because she wasn't sure if I was contagious. People sometimes are cruel. But the rash is harmless. Mel Saturday, June 14th, 2008 at 20:24:13 Wow! It is great to have so many people talking about the same thing. My youngest son is 4 weeks old today and he gets this rash constantly. It is really hot where we live but he even gets it when he is cool. I have found, like Jill, that it is with skin contact; mostly mine. I too, was wondering if it is my body wash. We already use dreft and my diet, as I am breastfeeding, has been very healthy. I dont know what else it could be besides body wash or heat rash. Hmmmmm? Any other ideas or confirmations? Jill did the change in body wash help? Kelly Friday, June 27th, 2008 at 20:10:06 Jill..maybe your baby is allergic to your parfume?..my baby is allergic to some parfumes and dyes in fabric..expecially colbalt blue..his dad is allergic to frebreeze and blue dye..and he gets heat rash too..but not like in the picture..it's more spread out and lighter..he's 10 months now and has just recently had a reaction to something..i'm thinking his new clothes..doctors are really usless..x Ema uk Wednesday, July 2nd, 2008 at 04:10:49 My Baby is just an month old, we leave in Las Vegas, 110 degrees average for summer season. My baby has a litte bit in her face, and more in her back near sholders. I was told it could be heat rashes, and It looks like Justin's rashes! I just hope it is, cause I also was told she might have food allergies! That is hard to deal with! Josie Friday, July 4th, 2008 at 12:47:34 Hi! My baby is always getting heat rashes. I rub calamine lotion on her to get it to stop irritating her back. If I wash the area first with antibacterial soap, lotion it up with baby lotion, then keep her in a thin t shirt and make sure she doesn't get too warm when she sleeps, it gets better after a week or so. I continued keeping her in the thin t shirts and she hasn't had a heat rash all summer. Good luck! kit Sunday, August 24th, 2008 at 21:30:47 Hi, was hoping that someone could tell me if their baby gets heat rash in winter? I live in Melbourne Australia and it's the end of winter and I think my baby has heat rash....it looks like Justin's rash...he's 6 weeks old. The doctor assumes that it's the heat rash. Mina Saturday, September 6th, 2008 at 22:26:47 My son suddenly broke out in hives, which brought me here. Although I know this is not the topic, I thought that I would share the fact that I am allergic to cold (and I live in Minnesota!!). it is extremely hard to do anything outdoors in the winter and often even fall and spring. I get large, itchy hives all over, especially in my thighs, upper arms and neck. It is helpful to read that others have similar allergies. I am fearful that mu son may develop this too, which is quite scary. Janelle Wednesday, September 10th, 2008 at 17:32:09 my 6 month old had a high temp for 2 days, then got a bit of a running nose, n a slight cough as i n my eldest daughter had just got over a flu i thought it was a flu also, then a rash apeared, a rash that to me looked like measles or somthing like that,omg i was stressed, i took her straight to the doc, he assured me it was heat rash and said i nd too cool her dwn n to do so i had to put bear min clothes and bath her heaps in cool water i did that and the rash nw is comming and going,its still a worry as it looks so nasty, but i trust my doc i believe she will come good, the rash to is under the skin, has anyone else noticed that???? thanks for reading my post... kelly Tuesday, February 17th, 2009 at 20:32:09 Hi my daughter is 6 weeks old and has had a very similiar rash. It is mostly on her face and chest area not on her arms or legs but living in a humid area she is just in little body suits or just a singlet and nappy most of the time. It has been persisitant for about 2 weeks now and doesn't seem to be going away. It seems to flare up if she gets hot or upset. I am going to change my laundry detergent and baby wash tomorrow and see if it makes any difference. The doctor seems to think it is heat related. But with my luck and doctors at the moment who knows!!! Cathy B Saturday, February 21st, 2009 at 03:11:42 I was actually replying to chelsea,I have what you have. it is all over me by the time i get done doing anything strenuous. sometimes just me getting hot from being nervous is all it takes. I just mopped my 2100sqfoot house and i am head to toe rash. I would love to talk to you more about this chelsea if you want to chat let me know. erin Saturday, July 25th, 2009 at 15:57:47 Hi anna my son has a rash all over his body that comes and gos when he is out in the son or upset do you think it could be fifths disease when he goes out side he breaks out in a redness all over his body like a real bad sunburn then when he gos back inside it slowly gos away AMY Sunday, August 16th, 2009 at 19:25:59 use camomile lotion.. n loose cloting... preferablyy cotton.. keeping baby cool emma Sunday, October 11th, 2009 at 08:00:56 hi i`ve been looking on the internet for a rash similar to my son`s, it looks alot like your little ones, he`s two and it looks to me like a heat rash, im a little worried as i took him to the docs and they told me its not a common virus but yet doesnt know what it is. he has had a heat rash more or less from being a baby but this is the first time its come up this red and angry looking, it seems to be itchy sometimes and have used calamine cream but other than that he seems to be happy enough. is there anything you could suggest what it could be or something i could give him. the doctor also said if its still there after 3 week to see a dermatologist, thanks samantha Wednesday, November 11th, 2009 at 10:55:48 Hi my name is shauneese My baby has this rash that i don't know what it is i took him to the clinic twice they gave him the same thing over and over but i just don't seem to work so today (21/02/2010) i took him back they said that maybe i should go and see a skin specialist cos they not sure that the problem is coz the treatment is not helping we are also using calamine lotion to dry it up , but it looks like HEAT RASH Shauneese Monday, February 22nd, 2010 at 03:50:59
