Has anyone else too expereinced shooting knee pain suddenly while walking at certain angle or may be lifting the leg slightly with rotation(by mistake).

I am only expereincing this now- a week from when i started to lengthen.

If so, any tips/excercise to manage it?
for me hot water pack relaxes it but later makes it worse, so only cold packs and keeping legs straight is helping at the moment..would love to know other alternatives
