Hi Bob
Thanks for the quick answer. PT if i am correct refers to the other ligaments around the kneew joint? Sorry I am not really well-versed with the terms.
You could be right when you say there might be a rupture but the feeling of giving away or pain occurs only at one certain angle. Also there is no swelling which I had previously when I had ruptured it the first time(my knee joint looked twice its size then)
Yes when I fold the knee there is distinct pain. I am thinking of giving some of my regular activities like running, cycling etc a rest for some time and see how my knee scenario progresses. I had given badminton a rest for a long time but the fact that I could do so many activities spurred me to try to play it again. .... and I am facing the consequences now.

If you do have any suggestions regarding anything I should avoid doing or continue to do, and food wise as well to help reduce the pain, do let me know

Cheers
Birdy
