Hi Barney...just so that you know there are others on here... I make a reply but unfortunately I was not offered Lidocaine, hopefully there may be someone who has and may be able to join in the discussion with you. I have total saddle numbness which means you could stick pins in and pinch the skin together with your nails as hard as you might but I have (Total) zero feeling....So Lidocaine would not be helpful or am I missing something here??.
It really is a case of finding out what there is and what works the best, to a certain extent it's pure experimentation because there doesn't appear to be any laid out route in terms of treatments and medication - I suppose it's because we are all different....keep trying, I find talking with the pharmacist can be a great source for information....By the way, whilst I have complete numbness I can still suffer the awful effect of compaction, in other words..."The tennis ball in the butt" - I get some good relief by taking "Fybogel" on a daily basis....it works for some and not others, like I said, it's finding out what works for you isn't it, best of luck.
