Boniva and baseball bat

I started taking Boniva 150mg Jan.1,2008.I followed directions. By Sat.Jan 5t.I woke up thinking I was paralyzed.It felt like somebody beat my legs with a rubber mallet and I had been hit behind the knees with a baseball bat.To this dayFeb10,2008 the pain has never gone away.I only took this medication once and my legs are still in severe pain everyday.It hurts the worst after I sit or lye down for a while.It feels like my legs have been poured in concrete, they are really heavy and whenever I sit or stand up ,it feels like my knees are breaking. I would not wish this on anybody,it could be used as a form of torture treatment if you ask me. If you have ever had any experience like this from this medicine please email me and let me know if it ever goes away
