I was hit by a car about 15 years ago and one of my dominant-hand wrist ligaments was partially torn when I was knocked to the ground. I opted not to have surgery and was told that physical therapy and keeping the surrounding muscles strong would help stabilize the area, increase mobility, and hopefully decrease the pain. I still do my home exercises when it starts hurting again. It took about 5 years for the pain to subside enough that I didn't want to chop my hand off.
The second time I was hit by a car landed me in a wheelchair and on crutches that I still must use (which of course aggravates my wrist issue). It was after more than a year of intense physical therapy and daily home exercises that some of the tendon inflammation began to settle down enough to not have multiple daily spasms. Perhaps a bit more extreme than your situation but the healing process is often not quick.
I'm no health expert but I can highly recommend watching Disney videos while doing mind-numbing and uncomfortable home physical therapy exercises. I've also found that a heating pad or warm water and gentle exercise helps with morning stiffness, though I don't know if that is recommended at your stage of recovery. If you were recommended to do exercises, do them all as many times a day as you were prescribed (and slowly too because many people rush through them).
Also don't be afraid to ask your physical therapist what his or her opinion is and what is the typical progress his/her patients make with similar injuries. I also found it helpful to do physical therapy only once every couple weeks if I was able to do most from home and then go in to be reevaluated and my exercieses made more difficult...since insurance normally limits the number of visits.
Hang in there!
