I bruised my right hand last August. My thumb got swollen and was painful to move. My hand looks completely normal now, and has full range of motion (I think, I am left-handed and my left thumb is more flexible, I can t remember if my right thumb had as wide a range of motion before the injury), but the big joint at the base of my right thumb hurts when I put my thumb inside my other fingers and make a fist. If I strain this joint or put pressure on it by really bending it, it causes discomfort. After six month, should I still have discomfort? Additionally, I am constantly cracking the knuckle of that thumb.
