<s>[INST] I am trying to learn as much as possible about pain pumps as I am considering having one implanted due to 4 failed back surgeries back in 2010. I have been suffering chronic back pain ever since and have tried every other option available with no success [/INST] Hi, dear. I have gone through your question. I can understand your concern.  You should search for the cause of back pain. You may have some disc prolapse or some vertebral problem.  You should go for MRI spine.  This will give some idea regarding  your cause.  Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health. </s>
