sun spots

A few months of go i lost my insurance and i was able to have my last  visit regarding spots that were white and dry on the back of my arm. i was told that they were just from sun exposure and a fugi that grows beneath the skin. i used both selsun blue and lotrimin. the ones on my arm went away very quickly but i now have some on my face they are more dry and far more bothersome because its on a more sensitive part of my body. i live in florida and experience lots of sunexposure. BUT selsun blue or lotrimin have not helped i have been having to put eucerin to calm the irritation and itch. is this different then what i had on my arm . please help i cant afford to go to a doctor unless i NEED to. if it is the same is there any other sensitive solutions to rid myself of these dry white spots.
THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hello,
Tinea versicolor is caused by a fungus that lives in the skin of almost all adults. Factors that can cause the fungus to become more visible include high humidity and immune or hormone abnormalities. Treatment involves topical and oral antifungal medicines. Most cases respond to over-the-counter products, which contain any of several basic ingredients: miconazole, tolnaftate, terbinafine,ketaconazole and clotrimazole. You can consult a pharmacist and get any cream or lotion containing these ingredients. Some of them are Lamisil, Monistat derm, Mycelex, and Nizoral.

I sincerely suggest you to discuss these treatment options with a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
