Hi, I have a concern about a bump on my left wrist. About 4 years ago that was diagnosed as ganglion cyst and was removed. It came back one year ago, and since then I have it. I went to a doctor (another one), had an MRI, x-ray, ultrasound and the doctor told me it s just a bone. But it hurts when I move the fingers. How can I be sure what it is?
