Please help

I am getting a red rash when my body  temperature change.  The rash appears on my arms (inside only), on my chest and neck.  it doesnt always itch.  it goes away after i cool off.  this also happens w/ emotional changes, as when i get upset or frustrated or nervous.  i also get itching sometimes w/ no rash that travels from my feet up to the top of my head and i become so itchy i have to stop running (it happens when i am running)or if i walk fast .Every times it happen it start: I fell itching then after that comes the rashes. I have this problem 5 month. 1st when it start to happen was everytime when I was trying to do some activites like sport or something like that but I only felt week itching and time after time itching were stronger and stronger so now I have itching + rashes. Everytime this happen i never sweat..actually since this start to happen i never get sweat. I get sweat only on my forehead. I try to see what will happen to run no matter the itching or rashes are coming so i run and run rashes come and itching was stronger and stronger but after 10-15 min itching were gone and rashes too. That happen everytime i try this. And after that no matter how much I run I dont get sweat. I use to wear earings for 1.5years and one of my friend have told me that the earings might contain nikel and maybe that is the reason of the problem so I took of my earings 1month ago but I still got this problem. What can be the reason of this and what can I do to this go away? Please help

Hi,

What you describe seems like sweat dermatitis or heat rash.

You should try to keep the area dry and clean. Try some powder to absorb the sweat. Use a medicated sunscreen lotion - preferably one prescribed by your skin specialist.

If the symptoms are still persistent, consult your dermatologist and get a proper clinical evaluation done.

Let us know if you have any doubts and keep us posted on how you are doing.

Hope this helps.

Good luck.
