Hello,
Without examination,confirmation of a diagnosis is tough but it can be dermatitis,keratosis pilaris or eczema.
Eczema is a form of dermatitis, or inflammation of the upper layers of the skin. Symptoms include dryness and recurring skin rashes which are characterized by one or more of these symptoms: redness, skin edema (swelling), itching and dryness, crusting and flaking.
Keratosis pilaris is a common genetic follicular condition that is manifested by the appearance of rough bumps on the skin like goose bumps. 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.
Treatment for all are different.So I would recommend an examination from a dermatologist to confirm a diagnosis.
Hope it helps .Take care and pls do keep us posted in case you have any additional queries.Kind regards.
