We both - husband and wife, have been experiencing these
symptoms. We have been on simvastatin for (wife for 1+ years, me for 2+ years) and stopped about 5-6 months ago - wife still having pains in the butt some dizziness and leg pain, but getting better - I am having butt pain and leg pains, swollen left knee, (but joint pain seems OK on stairs), recovery seems slower than my wife's.
