Lovastatin and cold turkey

I was taking Lovastatin for four years. After three years I developed severe leg pains and thought that it was all part of getting older. I didn't make the connection between my pains and the medicine so I continued taking it for another year. Finally I did the research myself and made the connection and immediately stopped the medicine cold turkey. I never would have started the medicine if I knew this was a common side effect. The pain started to go away and I thought I was going to make a full recovery. It has now been a year since I stopped taking the medicine and the pains are as bad as ever. My new doctor has started looking for other causes for the leg pains. Does anyone know if this side effect could be permanent?
