There are many medicines that you can take other than neurontin and vicodan. There is a new medicine called lyrica that is a similar medicine to the neurontin but it is seeming to have a better affect on patients with specfic neurologic disorders. My mother and step-father are both being treated with it and they seem to be feeling better and are having less of the siatic pain that they had become accoustomed to.
As far as other pain meds, there are a slew of them on the market and many are much more effective than vicodan/lortab. There are several that have ibuprophin in them like vicoprophin (hydrocodone and ibuprophin), combunox (oxycodone and ibuprophin) and then there are neat medicines that are just the narcotic like hydrocodone or oxycodone in a certian milligram dosage. There are also many long acting medicines that may be indicated in your treatment like oxycontin/duragesic/kadian/ms contin and many others that would between a 72 hour dose to a 12 hour dose and then you could be prescribed a breakthrough med like vicodan or even darvon if the sutained release medicine is very effective and you experience little to no break through.
If you go to Spineuniverse.Com you will be enlightened as to your specfic condition and also the many forms of treatment being offered for your disorder.
Good luck and remember, let your doctor be the doctor and let him/her make the recommendation as to the medicine you need, it may raise a red flag if you go in with a ton of medicines that you would want to try and it may backfire. Once you are a chronic pain patient, it is necessay for you to be very prudent when speaking to the doctor, if you are in pain, make sure they are aware but be careful that you always take their advice and professonial opinon to heart and if you feel that you are not being treated fair, do not be angry with them, try to find a pain specialist that is trained in the art of managing pain.
