Fosamax and gyno

Well, this seems to be a side effect I have not seen before or read about. I'm 67 years old, very blonde, tiny and petite---a runner and in excellent health. After pleading with my doctor for years he finally scheduled a bone heel test last year that indicated no bone loss had occurred. Three months ago my doctor finally prescribed a bone density MRI performed and whoopie-do, I have major bone loss! Two months ago I was put on Fosamax 40 to be taken once a week, a 5000 unit Vitamin D capsule and 500 mg's of Vitamin C to be taken 3 times a day. I have trouble swallowing along with dizzy spells , my stomach pain is severe and feels as though it's on fire. Also, my eyes seem to be much more sensitive and feel dry. I called my PCP last week and he said "not to worry, it takes time to adjust". Today I had my gyno appointment and the doctor indicated I have fecal bleeding. Since I have a colonscopy every 5 years (most recent was last year) I am positive it is not a bowel problem. Has anyone heard of bleeding from the stomach while taking this medicine? My gynecologist seems concerned, my PCP does not. I am wondering if a well-balanced diet with lots of calcium products would not be just as good---probably a lot better than taking this medicine and making Merck and Company richer than they already are. All I know is I felt a lot better BEFORE taking Fosamax 40.
