Is it normal to have round red spots under the armpits without any itching or pain?

Hello,

Welcome to icliniq.com.

I understand your concern. This condition is known as pityriasis versicolor. It is a form of superficial fungal skin infection. The color of lesions can be dark or hyperpigmented, light or hypopigmented, red or erythematous. Different colors can be there so it is named pityriasis versicolor. These are usually asymptomatic; one can see fine white powdery scales by rubbing the surface with a finger. I suggest you Capsule Itraconazole 200 mg once a day for five days. Nizoral (Ketoconazole) 2 % shampoo applied at the time of bath on lesions, leave for five minutes, and then wash it off. Do it daily for one week and then twice per week for the next six weeks. The lesions usually take six to eight weeks to subside completely. I hope you find it helpful. Kind regards.
