hard lump on right wrist

I wonder if you could be getting some arthritic changes in your hand..ALso, if you have ever had an IV in that hand it can leave bumps that hurt as well..I have two and can't remember what the the doctor said I want to say calcium build up at injection site but don't think that correct..Also am wondering if a Bone Scan would be something you should have done..It just shows how your bones and what kind of changes if any are going on..It doesn't hurt and takes litterally a couple mintues..

I have the same thing. I had tendonitis and had OT where they gave me excersises, ultra sound and a steriod injection. Finally got the inflamation under control then I developed a lump on the side of my hand almost were the wrist bone meets the thumb bone. Its hard and when I pinch it it feels like a mass not fluid. I thought it was a cyst. Not sure now. It doesn't move under my skin either. Not sure if I should get it checked or not. It doesn't really hurt unless I hit it hard.

it could most likely be a ganglion cyst as its most common in women in their 20's-40's
