osteoporosis
"Do not use this drug or any bisphosphonate. The first year I used it  3 of my fingernails had lifted off their nail bed. The 2nd year I got osteonecrosis of my left lower jaw. I loss 3 teeth, cannot have implants due to poor bone quality. The 3rd year my doctor had decided not to give it to me. I still suffered side effects of this drug. I was standing in one place ironing a shirt when I heard a pop in my leg and could feel my femur moving over.  That was 2 years ago and my femur is still fractured.  I just had my 4th surgery and hoping this heals my fracture."
