I am experiencing grating sound in knee from past 9 months. After MRI they said my acl got stretched, that was during the 5th month. Next I did shortwave diathermy and ultrasound massage and hamstring exercises, for around one month. Which did not improve my condition. Next my
vitamin d was tested and found out to be only 6ng/ml. From then I am taking vitamin d supplements and it's been 2 months but my condition is not improving. Can there be some other diseases.

Also I never hurt my knees for my acl to be stretched except some yoga and shuffle dance, there was no sort of dangerous movement done by me.
