I too have been suffering from this for the last 10 years, some tiems you can go weeks without any pain (even months!!) then you knwo when you going to get a bout of it, mine is numbness is my knee cap and pins and needles in my foot I had this happen once when i lived briefly in spain (company paid medical expense are such a blessing) After spending ages trying to lie down and not wake my girlfriend with my constant movements, i tried lieing on a hard flor, bending everything i could and nothing worked, the slightest movement woke me in pure agony, the movement of my ankle to bending my knee But my cure was a short taxi ride away, popped to a 24 hour clinic (at 4am) and apologised for waking the doctor up, he lay me down and asked me to lift my leg (i manaed about an inch if that), he looked at me grabbed my foot and lifted, and i have to say i damn near passed out from the pain, he then gave me the sweetest feeling needle into my back and within 60 seconds the pain was gone, went home to sleep and awoke the following morning and was pain free for following six months Sadly i am now suffering from it again and currently awaiting my physio Orthapedic triage (my second in 2 years) so i can have physio again, Pain relief works (pharmacy strength co-codamol) but leaves me too stoned to even work these days!
