Ligamentum teres strain & hip joint effu

While doing the yoga, I abruptly released the triangular pose on left side that caused the swelling on back side of the knee. While taking the medicinal course, the pain is like on and off for me for both the legs since 2 months . I used the shorter size knee cap unknowingly. From then since the thigh starting area, I am getting severe pain and muscle spasms and couldn't sleep for days. Recently mri of hip joints is taken. I am attaching the report here. Right now I am taking a pain killer and deflazacort 6mg mrg and Nyt since 3 days. There is no improvement. I couldn't walk and travel also. I have this fear like will it become normal? And in how many weeks? Is this a lifetime problem? Can I do yoga ever in my life? Bcz I have pcos too. Is it bcz of pcos, it isn't healing?
