Thank you johnmaggie11 and kevscar for the information. I believe skin ulcers is what I have. They cover both arms and my left leg. I also have them to a lesser degree on my left foot, the left side of my neck, my left eye, left breast, and my belly. I have been taking Hyperbaric oxygen treatments for the last week. I am seeing some improvement. I have many more treatments ahead. I am sure the HBOT will help me beat the sores once and for all.
