I developed such prickly heat like eruptions almost at the age of 14-15yrs. I had visited dermatologist then, he said its because of metal allergy. May be gold. I was told not to use gold jewellery. I did so but the eruption was not gone. Ever since it it there. Now my weight is increased by 20 kgs. And i hav pcod and acanthosis nigricans. Bt if i reduce weight, is there any treatment available which can cure it completely. And i can get natural skin back?
