I hit my knuckle about 3 weeks ago on a metal bin that I was hammering at full force. It was immediately swollen, which I assume is normal after an injury like that. My problem is, that 3 weeks later its still just as swollen and, almost at random it will flare up and hurt again at what I would say is a 5 or 6 in pain for a couple of hours. When I lay it flat it is almost as if its just the skin flap has gotten bigger or something, and its my pointer finger, right hand , middle knuckle. What could be the cause of this?
Hello, I understand the pain you have been facing. Usually pain and swelling subsides within two to three weeks after an injury. I would suggest a X-ray hand AP and oblique views to rule out any fractures. Slightly elevate your hand so that gravity doesn't act, you can keep your hand on chest during sleep. I would suggest anti-inflammatory Chat Doctor.  This should be helpful to you. Local painkiller patches of diclofenac can also be applied at the site of pain.
