About two years ago I had intense pain and knocking sound in left knee whenever I used to fold my leg, walk, or do any activity. Upon medical consultation and x-ray I was diagnosed with Left knee Chondromalacia Patellae and
vitamin D deficiency (PFA the report). After physiotherapy the pain went the sound remained but it was all good. But ever since the lockdown began the pain started returning slowly and now even if I walk for 5 minutes I experience too much pain. Even the left heel has started to hurt for the past few days. Please help.
