exercise induced rash

[jifnif]

I dont know if anyone can help me but here goes.  I am a runner for the past 20yrs and i am 36 now.  i developed asthma approx 7yrs ago and was on singulair and an inhaler until i read that singulair can destroy your muscles.  i went off all meds including ones for seasonal allergies except for the inhaler because of this and now trying to conceive.  Well, now while running or any elevation in blood pressure i get a rash on my arms, legs, and chest.  I find it difficult to breathe of course but am more worried about my rash.  My allergist has no idea.  This happens upon any thing where i use exertion.  any help is greatly appreciated.

I have the same problem.

In just found this on another site which kind of makes sense. Going to try anti histamines

"Not that your experience is normal, but it is more common than you think. The first thing to do is check any new clothing detergent or soap that you use. These products can cause allergic-type reactions in some people. If you rule out detergent, soap, or any other lotions, then you should consider a possible allergic reaction during exercise due to the release of histamines. It's not that you are allergic to exercise, but rather that you may be experiencing a biological response during or after you work out that mimics an allergic reaction. Here's what could be happening and why.

During exercise, histamines are released. Histamines are proteins involved in autoimmune responses like an allergic reaction to pollen or dust. People who are sensitive to histamines can experience rashes, itching, and other allergic symptoms during exercise just like you are describing. Most of the time, the rashes appear on the chest and thighs, but they can appear on the neck or arms, too. Sometimes exercise also reacts with food allergies or medications (for example, antibiotics, pain medications, sedatives, tranquilizers, and diuretics) to cause the problem. The problem typically occurs more in cold weather than warm.

If the problem bothers you so much that you can't stand it, or it's not resolving on its own, then you should ask your doctor about using a topical ointment to stop the itching, or taking an over-the-counter antihistamine like Benadryl 30-60 minutes before exercising. If over-the-counter antihistamines make you sleepy, your doctor can prescribe a non-sedating antihistamine. You should not take over-the-counter or prescription medications for this problem without speaking with your doctor.

Take care. Thank you for your question."

is it possible to get a rash on your private area then kinda...and be sensitve in that area all of a sudden. I just started a job where i have to run for hours upon hours and i had two days of 12 hour shifts in a row and now i have a chaffing issue.
i sweat alot especially because it has been verry hott outside lately.

I think I have the same thing.  I never used to exercise until about two months ago and every tme i do i break out in a rash that is so itchy.  None of the doctors can figure it out, but I read in another forum it could be Cholinergic Uticaria.  It also comes with stress.  I haven't found meds that work yet, I hope you do.

I get a rash when I walk, but it only seems to happen when my legs are exposed.  I don't seem to get the rash when my entire leg area is covered.  I'm not sure if the sun has any part of it, but this has happened at night.  I believe it may be from circulation.  The only way it goes away is with a very cold shower and nonexposure to any clothing that is itchy for about 15-20 minutes.  Does anyone else have this problem?

Thanks thats exactly what i think my troubles are.  Do you think it has any connections w/ adrenals?

I was getting a rash everytime I sweat while running on the treadmill. I went to the dermatologist and he  told me it is because of exercise. There is something that happens with the body in some people  when they sweat they breakout in a rash. I take it a little slower now. I hope this helps
