[|Human|] On the inner side of my knee there is a recurring blood spot that appears under the skin. It is bright in color then starts to fade completely. It reappears a few days later, the shape of the blood blotch changes each time but it is at the same place and very red like blood. What is this? It doesn t hurt but it has a cycle twice a month of reappearing. Sometimes it is in dots and it showed up this morning again and now it is a solid blotch. Sheri Gallagher
[|AI|]  Dear Sir/Madam have gone through your query and read your symptoms. In my opinion, your symptoms are quite peculiar. This could be hematoma, which is presence of normal tissue at an abnormal site for that, or it could be vascular tumor. We normally proceed with MRI a non-invasive way to see what's inside, The conformation is usually by biopsy. The treatment is surgical excision or chemotherapy, depending on cause and extent. I hope that answers your query. If you want any more clarification, contact me back.
