Gave my hand a wallop about 5 weeks ago. Became very swollen and bruised, still had most of the movement of the hand only very painful if touched. The bruising and the swelling went down excepted for a lump.
Now I have a very small lump and occasional pain when touched in certain ways (putting my hand in my jeans pockets is the normal one). Today a small boy put his weight on the back of my outspread hand and it took me by surprise that it really hurt.
If I did in fact fracture a bone in my hand is there really much I can do about it now.
