My joint where your thumb connects at the base to the rest of your hand, hurts like hell not all the time but if i move it a certain way its intense pain. Today its kinda constantly there, so was tapping around the area to see what hurt and it was right where your thumb has little bump at the very base of your thumb.
Basically if I try to twist a cloth to wring it, i have no strength and if I push it or do different things its excruciating
