weird mark on arm?

I have some weird red marks on my arm, theyre quite large and feel rough to touch, image here -> http://imgur.com/42wMChk

Looks like a rash of some sort.  Have you eaten anything you would not normally eat?  Try a food diary to see if a food is the problem.   If it doesn’t go away, I would see your doctor. 

Hi j44535

Does the rash itch?...

No itches, just rough.

will try, thanks

Hi j44535

I think it could be a fungal infection..you should get an anti-fungal cream from the pharmacy or doctor.. best wishes...

Good luck.
