dear doctor, I am 64 years of age. I have had crohn s disease for nine years and coeliac disease for 30 years. I have also experienced oral crohn s disease which has been difficult to treat - this includes mouth ulcers and a swollen and painful jaw. I have had several courses of glucocorticol steroids over the years. I am currently being treated with Infliximab. I also have osteoporosis and recently suffered a spontaneous fracture of one of my vertebrae despite being on fosamax for nine years. It has been recommended by an endocrinologist that I have an infusion of aclasta. Reading the side effects of this medication has made me very nervous about this treatment particularly the osteonecrosis of the jaw. What are your thoughts? thank you, dawn email is YYYY@YYYY
