SEE A DOCTOR. No joke. I sprained my ankle really badly a couple years back, and without physiotherapy I'd still have scar tissue in there. But I'm fine and haven't even felt a twinge since. Also, this past summer I broke my collarbone playing soccer, and I thought it was a separated shoulder for like a week. All of my co-workers were advising me to see a doctor since I couldn't even move one side of my body, so I did, and I had a fracture. I would've had to have serious surgery if I hadn't seen a doctor, so yeah. SEE A DOCTOR.
