Hello~Sometimes Statins can cause this, and even when stopping, the pain may not go away immediately.
I have one suggestion, possibly seeing a chiropractor will help this issue. The chiropractor will take x-rays of the area, study them and then go over the results with you. Sometimes a few treatments are all a person needs to get back on the road to recovery and being pain-free.
I would also try adding an extra supplement of Vitamin D3 and a good multi-mineral complex to your daily diet, if the body is deficient in these, then pain can certainly be a symptom.
I hope you feel better soon.
