I have a blisterlike bump on the first knuckle of my index finger. It appeared rather rapidly and I thought it was due to arthritis, but over this weekend, it has developed more bumps and seems to be filled with fluid. What is it? And do I need to see my doctor?
Hi ! Good evening. I am Chat Doctor answering your query. The bumps on the fingers could be due to some kind of arthritis (specially rheumatoid arthritis). The diagnosis and treatment of these bumps might not be possible to be elaborated over net without having a physical examination of the same. Therefore, yes ! I would advise you to see the orthopedic specialist in your area. If there is pain, you could go for some anti-inflammatory Chat Doctor.  I would also advise you to get routine blood tests like CBC, RA factor, ESR before rushing to the specialist. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor.
