I had a lump come up on the top of my right hand then disappeared after a week or so. Since then I been having a bad pain in the right arm. Im not sure what it is, hoping it would go away but had for about 5 weeks now
I do not think I can really give you an answer based on the information you have provided. The pain has continued for 5 weeks now, so I think it is now time to make an appointment with your doctor for an examination. I doubt the lump is relevant as it has disappeared but without a detailed history of the pain and examining your arm and hand, I wouldn’t like to guess what it may or not be.
