Hey
Been reading your posts with interest for a while now - totally jealous of your shed time!
Really sorry to read about your back injury, that shit sucks. I can sympathise as I blew out two discs last year which protruded onto my spinal cord - the pain down my leg and foot was just insane; pretty much started eating tramadol like m&m's.
Anyway, there is a point to this dribble @yetchh mentioned above... after trying high dose steroids and being told I would probably need surgery, someone put me on to inversion therapy (basically hanging upside down by your ankles) This shit works! I went from hobbling around like an old git, to fairly well sorted within a few weeks.
So there you go, a bit unsolicited advice from a complete random.
Loving the Crown BTW
Cheers James
