I had it in the past too. I went to a teaching hospital to see a dermatologist but they gave me a long list of tests to go and do. Luckily, a good friend of mine linked me to one AB BUMPS clinic. They tried their best at least by reducing it to a reasonable level. Since, little of it still appeared from time to time, I started applying NEO MEDROL AND NEO PRESOL. These drugs have made the stuff to disappear. But you have to continue rubbing these drugs or else, it will reappear. But, firstly visit AB BUMPS.
