In the knee below the cup and inside to the knee I feeling pain when straight or fold the leg for about 15 days. I have hypothyroidism and taking 87. 5 mcg. Recent 20 days ago I am taking zandu (vit d) (weekly once), folvite 5 mg (folic acid once a day), glacizyme (2 times a day), tetracycline cap (2 times a day), xl-mont (once a day), nurokind 1500 (one a day). What is the problem? Why I am feeling pain? I had this type issue in below hip pain while walking 2 times in these 5 years and after taking some vitamin caps the pain was gone.
