Hi Grockle sorry to hear you are suffering in such a way.
Have you been refered to a pain clinic? What dose amitryptiline are you on? If it's not working go back to your GP and ask about upping your dose. With a herniated disc and associated sciatica you also need to get to a physio (DP's resolved within 8 weeks after a combination attack of amitryp and physio) but it was truly horrible watching him go through it.
Me, I have fibromyalgia and get sciatica down both legs and 'sciatica' down both arms, I am on 50mg Nortryptiline daily (2 in the morning and 3 at night) and take diazepam and codiene when I get a nerve pain attack. The trick is preventing them rather than treating the pain so avoid known triggers - I can't swim as this sets my arms off, and walking long distances sets my legs off.
I would say I am coping, I was, but i'm not anymore. I hate being like this, I was in tears on Sunday at how useless I feel. I'm exhausted, being in pain is wearing me out and wearing me down and I want it to just stop :(
Sorry I can't help. I know the 'theory' of how to help but really, it's so so hard to put into practice :-( My tips:
Get a good GP/Pain Clinic Dr who listens to you and can work with you to get a good medication regime
Physio, Physio, Physio - don't underestimate this!
KEEP GOING! Seriously, rest is very much over rated, keep going until you want to stop, keep going that little bit more THEN stop
Heat and Cold
CBT
Someone will no doubt come along and tell you thats all crap and don't do it, but it's my way of coping :o or not. :o
Good luck!
