osteoporosis
"I had been on Boniva for 18 months and woke one night with severe chest pain and pain in my throat and jaw.  For the next three months I ran high fevers and suffered chills and incredible pain.    My internist denied that it could be this drug and didn't even tell me to stop taking it.  I have spent thousands of dollars on tests and nothing has indicated that it could be anything else but the drug.  The only way I have been able to function has been by taking Prednisone and tons of Advil.  Be very careful if you take this drug and if you get any of these symptoms STOP TAKING IT regardless of what your doctor says."
