I got an ACL surgery two years ago on my right knee. Firstly I was recovering a tough groin injury about two months in physio and then I decided to play some futsal. Of course my body wasn't well prepared to play intesively after two months without playing and in one play i was in great acceleration and some guy pushed me. I still managed to score the goal before he pushed me (great goal indeed!! without angle) but when I fell I immediately felt lots of pain. I usually don't care about injuries but this time I couldn't even return to the pitch. 2 hours later my knee (and thigh) was almost two times bigger than the other leg and about one month later (time to let the inflaction reduce a bit) I got the surgery (total snap).
After being 4 incredibly sad days in the hospital (probably some of the worst days of my life) I was about 6/7 months in physiotherapy, attending every day. Fortunately, I was motivated to recover it and I did everything with determination. I won't tell you much negative stuff about all of this because there is plenty and you might don't want to hear it, but you surely want to hear some positive things. Well, I think that your injury and the whole recovering period will change your way of relating with people. Precisely because you will need them and you are going to see who's really supporting you. Secondly, you will have some more time to do some weight lifting. Third, I don't know the way you are but you will turn into a more mature guy, even inside the pitch.
I've just read now (at the end of typing my text) that your injury is different than what you were expecting. Anyway, some guy who get a ACL tomorrow has my view here!
You will still have surgery, right?
