So...had a doctor's appointment today. It was just with my personal doctor and not a joint specialist, so she said she thought that I'd torn the ligament in my knee [I think she called it the MCL or something] or damaged the cartilege... But, she referred me to an orthopedist, so I have another appointment next Tuesday. They said I might have to have surgery depending upon how bad the problem is... Hopefully it's not that bad. I'll just keep praying that everything will work out.
