I do hope sciatica doesn't make itself known to you again Sarge as in my humble opinion it is one of the most horrible types of nagging pain one can suffer.
The two spinal ops I had way back when, relived the side issue of sciatica for me only for it to resurface a few months back.
I asked the quack how come t's back when the spinal jobby was supposed to have stopped all this nonsense?
It turns out (as I'm sure I have mentioned before) that this time around it was an inflamed buttock muscle doing the business and some more movement was in order.
Either way old soldier as long as it doesn't impinge on your hobbies too much then some solace can be gleaned.
If however climbing into small Brit mobiles cause problems then I can only suggest the following...
