Fosamax and rn

My mom was recently prescribed Fosamax. She took one pill in the morning and by that evening she as in excruciating pain in her shoulders and chest. She describes it as a burning, tearing feeling that is made worse by bending down or moving quickly. She only took one pill and it was almost 4 weeks ago now and yet the pain has not subsided at all. She had a chest xray last week with normal results and is going for a bone scan tomorrow. Anyone else experiencing these symptoms and what has your diagnosis been in regard to the symptoms.

I was on Fosomax for only two weeks and I experienced severe chest pains and the inability to swallow. I spent 5 days in the hospital on morphine until I was able to swallow and get liquids down. Even my siliva touching my esophogus caused horrible spasms to my chest. This is a horrible drug. What I found difficult to believe it that the doctors "poohed-poohed" the idea that Fosomax had anything to do with what happened to me. If it wasn't for my sister, an RN, who saw Fosomax being advertised and heard the warning of the side effects of chest pains and difficulty swallowing, I would have gone home from the hospital and taken another dose.
