I went to the doctors a couple days ago about a sprained thumb. They x-rayed my thumb and confirmed that it was sprained, but didn t show me an X-ray nor tell me what ligament or give me a paper, although they gave me a splint but didnt tell me how long to keep it on for. So i am trying to figure out if i sprained my ulnar or radial ligament in my thumb and how long it is going to take to heal. It hurts a little to grasp things between my index finger and thumb, but hurts more on the outside of my thumb if i try to move m thumb and there is pain and swelling and little bruising on the outside of my thumb by the joint.
