### output:

It is not that your spinal fusion got to do with pain, successful surgery will prevent all movement there and nerve impingement, so cause for pain is not it. Your doctor should gradually shift you on alternative painkillers if at all needed. Heavy periods and vomiting has got something to do with hormonal imbalance probably, and a gynecological consult is necessary. If USG is not finding anything, simple anti-emetics before periods must be taken and may be prescribed by genes specialist after giving you internal check and hormonal profile. If you are having abdominal pain, then maybe colonoscopy may be necessary for bowel symptoms/findings that has made your doctor think on those lines.
