Hi Carol, I think you can go to Search and type in Lesions and get the information you want. I've had two lesions, and they started out larger than a red dot. It got infected and was a long time and extremely painful to keep it clean and eventually get rid of the lesion-infection. My Dr. had me sit in warm water every few hours to bring the infection to the top and keep it clean. It's like an open sore. It was on back of leg, so my husband would keep it clean with q-tip. My Dr. said to keep it dry-not to cover it with band-aid and salve. That would prolong the sore, but keeping it dry was better. Hope this helps. Let us know how you are doing. Your friend, loretta
