Chronic pain since July 1996. I was on Brand Gabapentin (Neurontin) no generic at this time May 2000. Pain Management Seattle, WA. I was up to 1,200mg 4X a day. PM doctor said no limit to the dose. There is an awesome Face book group to help getting off of this medication. So much compassionate understanding and help. Please get off. I was also taking Brand Lyrica 300mg 2X daily a year ago. I was able to stop these 2 reducing fairly quickly. Many others go thru pure hell getting off. Group is Gsbapentin/Lyrica Withdrawal. Join for the support you need. In my opinion the Tylenol is worthless. Only destroying your liver and Kidneys. I understand the pain pump. If it has Baclofen in it get rid of it if you value your liver. That med is bad news. I assume the pain med is Hydromorphone? I take it orally 8mg 4X daily as needed for Complex Regional Pain Syndrome Neuropathy and other bone on bone destruction that they won't do surgery on for fear of neuropathy spread. Ketamine compounded nasal spray is used for migraines with a lot of success. It may not work well with Gabapentin or Fentanyl. You might want to check it out.
A protective bladder protocol should be followed as it is known to damage bladders. Another group on Face book for Ketamine is Ket-amine
For Better Health(CRPS, Chronic Pain, & Mental Health). Be sure to read the rules. They are strictly enforced. The word ketamine must not be spelled out. Use K, Ket, Ket@mine. May help you. It is not a cure only a tool. I have CRPS and get much relief from it. Do not just stop taking Gabapentin. You could have a Pseudo Seizure. Have to reduce slowly. I hope you find answers soon. Take Care
