Hi just wondering if anyone else finds this or can explain the following.I have serious spine problems,had one operation and waiting for another.had a car accident which caused a compression injury to the spine,which a few years later and in bewteen,has now caused protruding prolapsed disc,spinal disc and facets degenerative joint disease,sciatic nerve damage, serious pain and numbness in right leg.Alot of days I struggle to walk because of horrendous pain in my spine and leg,yet I compete in my local car club events in which you have to walk roughly 1/4 mile for safety talk.On the day I find I can do this with no pain. and get in and out of car.It is a high speed timed event.Sort of from the evening before and whilsy doing the walk and competing I have butterflies in my tummy and the sweats and need to pee lots more!!After the event I find the pain returns more severly for quite a while {24hrs approx) Is this maybe due to adrenalin stopping the pain or my brain blocking the pain !
