What Causes A Rash And Small Bumps On The Fore Arm?

I have a rash in my forearm with lots of small bumps on one of the arms it seems like I have a rash. the bumps really don t itch. I tried cream but they just don t seem to go away. I ve never had this problem before. I am dealing with TMD not sure if that would have anything to do with it.

Hi.
As per your case history you are having polymorphic light eruption.
My treatment advice is -
1. Avoid sun exposure and use a good sunscreen lotion with spf more than 30.
2. Apply a mild antibiotic plus steroid cream like fusiderm-b cream twice daily on it.
3. Take an antihistamine medication like levocetrizine twice daily for 7-10 days.
4. Other treatment options are oral antibiotics, oral steroid taken only after consulting a dermatologist.

Thanks.
