My Pain Management experiences.

I have a couple of conditions, peripheral neuropathy within my feet and spinal stenosis at L4/ L5, which causes further pain within my feet. My condition is that bad that I utilise a wheelchair to get me about as the numbness within my feet causes issues of balance along with chronic pain.
The pain is ironic, you can stick pins into my feet and I wouldn't feel it, put on my socks and it's like putting th into a bath of acid. I also manage to pick toenails clean off during my sleep, which isn't any fun when I wake up and realise what I have done.
Anyway, the reason for my post. Pain clinic.
The gp pushed all sorts of drugs my way, antidepressants, anti epileptic and the milder pain relief tabs they have at their disposal. All of them had a limited impact upon my pain but a lot of them had a massive impact upon my quality of life. Anti depressants making me depressed and suicidal, along with causing me to do strange things that very nearly Cody me my job. Other drugs making me feel zombied. Others just causing violent reactions. Suffice to say I had had enough after 2 years of being treated like a Guinea Pig. Finally I was referred to a constant at a pain clinic and the big guns were rolled out. I started on Fentanyl, finding that the cheap patches made my life hell but the branded ones were a life changer and helped with the pain. Once the balance was found regarding level of medication to reduce pain I experienced the first time since being diagnosed a pain free existence. I had gone from experiencing random stabbing pains around 20 times an hour to about 10 times a week' being an opiate there were sexy problems but they are outweighed by the improvement in the quality of life. Over time though I became tolerant and an ignorant GP made my life a misery by putting me through cold turkey, that was a horrible experience and now recognise I am physically addicted to opiates. Then the inevitable happens and the effectiveness wains and I have to be managed off the fentanyl and introduced to methadone, now I am officially a heroin addict, well opium addict more like, but I am alive and able to enjoy life with a massive reduction with the amount of pain I experience. Ok it's not brilliant as I have a numb stump of flesh hanging from the end of my legs but it could be worse.
As an indication of how good the fentanyl was as a pain med I had a finger bitten off just after the nail bed and didn't experience much pain at all, again another strange experience.
It's very late, my eyes are closing and I will leave it there. Any mistakes or typos are purely my own ????
