Gene pool symptoms and conditions

My fiance' has been on Lipitor for the past 2 years. Over the past 6 months, he has experienced extreme back, muscle, joint and wrist/hand muscle pains. He also has a very mild patchy rash around his mid-section (comes and goes). His hair has dramatically thinned over the course of his treatments and he has very little energy. Now, he is now experiencing sexual dysfunction. This is very concerning to both of us. Did I mention he's only 35 and clearly got the raw end of the gene pool? What is an alternative?
