Fosamax and 15 minutes

My doctor gave me Evista and it made me so constipated that she changed my meds to Foseamax I took it for 1 month and had a sereve cramp in my colon that I needed to put a heat compress on it for 15 minutes. Then 2 months had another bout only worse I could hardly catch my breath, again another attack a few weeks later. These were all when I was trying to have a bowel movement. My doctor told me to stop taking this medicine when I told him about other things that where happening along with the cramps. Things to grafic to print. One year later and I still have these cramps even though there are not nearly as bad as when I was taking the medicine. I received papers in the mail that said Foseamax was a drug for cancer. I too was told that if I didnt take this medicine that If I fell and broke my hip that I had a 1 in 2 chances that I would die. What a crock!
