This EXACT thing happened to me not too long ago (beginning of September) my injury came from an arm wrestling match, whilst drinking LOL (the shit we do when we're drinking)
I iced it starting the next morning, and kept icing for 72 hrs. when i tried to go to the gym a few days after the incident i found that i couldn't even pick up light weights without HUGE amounts of pain, also rotation of the wrist was an issue...i used an ACE bandage for the first month after the injury, and now for the most part i have full use of the wrist. it still feel like its weak, and i still get pain, and cracking noises when i rotate my wrist, but i try to avoid exercises that require any of those movements.
I used PT for my shoulder when i separated my AC joint (i finally caved and saw the PT after i was in pain for close to 8 months) i went to the clinic in the talisman center, and i really saw no results after a month, so i just stopped going.
have you asked your PCP for a referral to a sports medicine specialists?? im sure you are wasting your time discussing your injury with a PCP.
