You might go to the people who did your fusion and tell them an update. They may give a referral or start treatment for symptoms themselves. These days the go to drug in the Neurapathy world is Gabapentin. Some find relief to some degree and some have side effects that outweigh the relief. I started at 300mg/day and went up to 900. I have read that some go up to over 2500 mg/day. There is no clear roadmap to relief. Some other basics need to be investigated. If you are low in B-12 or vitamin-D, etc. I quit the Gaba but would go back and try a higher dose if I get worse. Good Luck, Ken in Texas.
