... debilitating the hurting is more than I can stand. - I was overweight,had gastric bypass in the hopes of relieving the pain. It didn't work. Now my Doc wants to try something called Calcitonen Intervenous Injection treatment. Should I worry about adverse affects? Long term problems?Anything I should worry about? (Treatment is just 3 days away) Apparently this intervenous treatment is done at the hospital ambulatory care takes 1/2 hour and then its done and works or doesn't work. Thank you
