I was playing soccer and planted my foot to take a shot after a long sprint downfield when I guess my body rotated, I heard a loud pop and went down in a ton of pain. It was extremely swollen and I could not walk for almost 2 weeks. I did not go to the doctor at all because I had no insurance. Anyway for the next year and a half it felt weak, would pop out of place every now and then and once I thought I reinjured it (got really swollen, but went away after a day). Anway I started training MT last may but only was able to go 1-2x a week for 2-3 months due to work, distance, getting married, etc. When I started I still felt a looseness in my knee but never hurt it. I started training again in january and have been training 6 days a week both MT and BJJ with no problems at all. I'm doing my first bjj tourny this weekend, and will also start sparring in MT this week. I really want to go full on with competing, so now I wanted some opinions. I am fully aware that I SHOULD have done something about the injury when it happened but I did not and that is in the past. But since it was so long ago if I am having no problems should I continue to train the way I am for as long as I can, or is it really something that I still need to get looked at asap? I don't think I could take the heartbreak of being out of commission for 6 months+ when I am really just starting to train how I've always hoped I could.
