You might want to add 800 mg Ibuprophen three times a day, it's an excellent anti-inflammatory and should reduce your back pain in the long term, but with migraines, you may run into a problem with rebound headaches.....also, it might be time to consider a long acting narcotic that does not have apap such as oxycontin or mscontin, this would need to be prescribed by a local physician, you can't get it via OP's, but would help with the back pain & reduce the possibility of rebound headaches, good luck to you
