Hi sharileedahl, I found a specific sport training facility in my area. My initial assessment today showed that my knee was really weak (obviously) and quadriceps and hamstring are also just as weak. He said the pain at the back of knee could possibly be from the muscle trying to compensate for a weaker muscle. My training starts tomorrow and will be 4 days a week. Hopefully I can get fully back into basketball just in time for my season. I wanted to thank you for responding to my post along with your advice. Take care.
