Thanks for your query
From the description of the skin lesions, i suspect that you have developed granuloma annulare
These lesions are more often seen on the sun exposed parts.
They are mostly asymptomatic in nature.
You might need to apply potent topical steroids
over the lesions.
But it is better that you get yourself assessed by a dermatologist
before starting any treatment.
Hope it helps
