Hello, The symptoms can be related to many medical conditions. One of the common conditions is rheumatoid arthritis. I suggest checking the rheumatoid factor level for further evaluation. Meanwhile, I suggest to use anti-inflammatory medication such as Ibuprofen 400 mg three times a day. I also suggest to use cold compresses for local application. Take care. Hope I have answered your question. Let me know if I can assist you further.
