Root tethering on basis of scar

Hi I have had two microdiscectomys over the last year and a half each time my symptons get worse. The pain I experiance is constant down my left leg and foot I wake up a couple of times a night with cramp like pain which is quite unbearable often waking my wife as I am shouting and screaming, in the day I have a constant pain which shoots all down my leg and my left foot has not been the same since my first operation (which is quite bizzarre as my original pain was shooting pain down my left leg and stabbing in my ankle but did not go into my foot). I get burning sensation on my toes and the bottom of my foot which is like someone putting a blow torch to it I am unable to drive now because of this I can't even wear shoes or trainers I constantly wear flip flops as these seem the most comfortable if I try to walk barefoot I am of-balance because my left foot feels like it is not mine. The medication I currently take is 2700mg gabapentin 1000mg naproxin 300mg tramadol and 25 mg amitriptyline. My last visit to my surgeon where I also had another mri was a couple of weeks ago he said that my discs didnt look to bad and that I had root tethering on the basis of scar. Hew added that another operation could fix it but he could also add to it aswell so does not want to go down that route just yet. He has now referred me to some pain clinic to see if injections will work he also said there is a waiting list so God knows when I will hear anything of them. I asked if there was some sort of pain relief I could take even if it was just something at night or when the pain is resally bad in the day he did not want to suggest anything untill I had been to the pain clinic. I feel like I have just been tossed aside as he has operated twice and not acheived anything (made it worse if anything) My GP won't give me anything else as she does not want to go against the surgeon so I was wondering what people do when the pain is unbearable as this is effecting my family life. I am putting on weight as I am not that mobile I am only 36 and my life has come to a bit of a halt. sorry for the long post but this is one of my coping mechanisms when the pain is bad I try to focus on something and ride it out
