Painful, Reoccurring Red Marks On Arms But These Are Not Itchy

He has had lesions (red marks) on his arms occurring and reoccurring for the last 7 months. Occurring once a month until the last month and a half when they have started occurring every few days. Painful an hour or two before showing on the skin , then they appear and then for the next few hours to 24 hours they are painful feeling like pinching (lighter red) and burning (darker red). Then they start to fade away and will be completely gone within 2 to 5 days from when they first appeared. For the first time a few also started appearing on both legs this past week. They are like a bruise but disappears quicker and when pressed doesn t hurt any worse but, he feels less feeling in this area compared to touching a different part of the skin. Tylenol and cold packs help very little with the pain. They are never itchy. They are painful when first appearing until they start to fade which is usually a few hours after appearing to a day or so later that they start to fade away. Then the red marks (lesions) will be gone completely from the skin within 2- 5 days.
