Forgot to mention that my doctor had prescribed Alondronic Acid tablets to be taken once a week. Reading the enclosed leaflet about side effects was very worried about taking it as have reflux problems and indigestion on a regular basis. My stomach has always been my weak point for as long as I can remember, including a suspected duodenal ulcer when I was working in London. I take the calcichew tablets every day. He was very adament that I should take the Alendronic acid as he said that my bone density would be plummeting. I understand his concerns but have not had a Dexa scan so don't even know what my bone density is like. Despite riding horses for years with the inevitable falls, I have never broken any bones, so always assumed that I had very strong bones. I would appreciate your comments when you have time.
