i've got problems with my knee too, 5 years ago while i was playing football in a sport hall i felt on my knees (mostly on my right one) and it fu*king hurt, i was not able to straighten my right leg without pain....i have gone to a doctor but he is a stupid one (ones one of mine frends broke a finger on his foot, and the doctor just wraped it with a bandage, he had to break him again) he told me that it is becouse of my years (13-14 yeras-it is normal to have some "gaps" between your cartilage and the leg(or the knee can't remember it), the muscles should fill the gap, but i alredy had muscles since i was training football), 3 years after the injury i could not do as much with my knee as i could earlier,and it still hurt. Nowdays it hurts sometimes, it depends on the weather (it cracks sometimes like when you crack your neck, but whenever i do a step it crackes again,and again,and again it feels like my knee is going to fall out)
last year i streched my ligaments(on my right leg), notihing much, just 14 days rest
Sometime this year i streched my ligaments again (this time on my left leg), this time one week cold compresses and 2 weeks plaster boot...i can't flex my foots as i used to do, but it is logical
NOW THE QUESTION:
should i do squats, couse i'm afraid (i could do with leighter weight) for my legs i like to do sprints, but i know it is not enough.
on monday i'm going into the gym so i have to know (so far i was doing street workout, but it becomes to cold for that)
PS. sorry if i made some mistakes, english is not my native language nor do i learn it in school (i learn german)
greetings from Bosnia :D
