I will do the stretches you have there - how much time should I commit to those. Should I do them once a day, or every time i train?

Should I still b stretching my quads and calves a lot? - I have read that tight quads and calves are often associated with patella tendinitis.

So do you think this is all related to my deteriorating eyesight? I am a bit short sighted but I feel like i cope without glasses easily enough.

Otherwise are you saying it is a bad habit i have developed which is now part of my pschycotic memory?

So if i am overworking my left side i have a tight muscle in the back of my right shoulder to my spine as a reaction to what? - weakening on the left?

So does this mean my knee and back problems are definitely related to each other? Which muscles would be weakened / strained / tight that connect the two?

I've found info on the net explaining how weak hamstrings or a tight ITB can cause tendinitis and lower back pain but since i have no lower back pain I'm not sure how it all works.

I'll feel better and more able to prevent another injury if i know exactly what went wrong so any more info or references for papers/texts/web sites which can explain this particular string of muscular mishaps would be fantastic!
