it name is prurigo nodolarisive got the same problem
Hello,
Without examination,confirmation of a diagnosis is tough but it can be keratosis pilaris.It is a common genetic follicular condition that is manifested by the appearance of rough bumps on the skin and hence colloquially referred to as "chicken skin".
Keratosis pilaris occurs when the human body produces excess keratin, a natural protein in the skin. There is currently no known cure for keratosis pilaris, however, there are effective treatments available which make its symptoms less apparent. Treatment includes tretinoin or Triamcinolone cream or Adapalene, a retinoid medication. Exfoliation, intensive moisturizing creams, creams and lotions containing alpha hydroxy acids and urea may be used to temporarily improve the appearance and texture of affected skin.
I hope that helps. Please do keep me posted on how you are doing or if you have any additional doubts.Warm regards.
