I too have back problems, herniated lower discs and take opiate based painkillers that really chill you out. Been offered an operation but when I was told what could go wrong decided to stick with what I`ve got. When the pain really hits it drops me to a heap on the floor and I have to breathe really slowly and shallow.
Trouble with the neck as well, I sometimes forget and do the stretch and twist of the neck , that brings really painful headaches, I feel like giving it a stretch with a rope from the stairs but if it went wrong could only imagine the news reports something like sex games gone wrong
Minds willing but body ready for the knackers yard
