Reddish Blotches On The Upper Arm. Dry Flaky And Itchy Skin. Reason?

After I shower I have red blotches on my upper left arm, started with a few, now has been spreading up my arm to my shoulder, and a few on my upper right arm as well. They are slightly itchy, seem dry and flaky, not too raised from the skin. I've noticed some whitening of my skin where the blotches used to be, now they have traveled up. What is this?

Dermatologist,  's  Response
Hi,
It seems that you are having tinea versicolor.
It is also known as pityriasis versicolor.
It is superficial fungal infection with varieties of colored patches.
It is caused by melassezia furfur.
It may be there fromlong time without knowledge.
After showering you got irritation on lesions , so erythema developed representing redness.
Gradually color changed to white.
Some time in other patients color may be black,greenish or yellowish.
There is good prognosis.
Take antifungal ..like ketoconazole or itraconazole.
Apply clotrimazole or miconazole cream.
Shampoo with ketoconazole containing shampoo.
Avoid soap bath. You can use dettol liquid for bath.
Keep the area dry. Perspiration may increase the disease.

I hope may be alright within few weeks.

Still, you may consult dermatologist.

Thanks.
