My brother has had these 2 red patches on his outer thigh for 2wks.some itching no pus.it look likes a rash.no hot or warm to touch.any cream to use?

Doctor can evaluate: Rashes are hard to describe or visualize using words. Patches on skin without much itching or irritation can still be a variety of things, including eczema, allergic reactions, chemical/irritant contacts, tinea fungus, etc... A primary care doctor can evaluate to see which cream or medication should be tried first. If it's eczema, the otc Hydrocortisone cream plus non-medicated cerave is helpful.

Difficult to tell: Skin issues are very difficult to diagnosis without actually seeing and touching the lesion. Occasionally, doctors may even need to biopsy or culture the lesion to make a determination. Best to see you family doctor or dermatologist to get you the best answer.
