Hello Dr. Prasad, I ve been having more noticeably dry skin lately. Last night I woke up because I my legs were itching so bad. When I looked at them, I had two small bumps, (one on each leg) at the spot of dry skin and the itchiness. They went away when I woke up, and they looked like bug bites, but they weren t. Today, I had the same type of bump show up, but on my arm instead. This one is still here and has the same characteristics: located at an area of dry skin, and is itchy. What could this be?
