I got flaky in my upper stomach and in my nails too. what could be the cause and the treatment? thanks

Doctor can evaluate: Rashes are hard to describe in words. Usually, a primary care doctor or a dermatologist needs to examine the rash to give a diagnosis. If fingernails are involved, a dermatologist can see if it is fungal (and do a culture), or maybe something else such as psoriasis. On the skin, eczema, pityriasis rosea, tinea versicolor, and psoriasis are some examples of disorders that can cause a flaky rash.

Many possibilities: Some causes of abnormal nail growth include trauma, infection, side effects of medication, and possible systemic diseases such as psoriasis. Get evaluated by a professional to determine the cause of the problem, as treatment varies depending on the diagnosis.
