Hi Rosie, sounds like youve been in the wars, back injuries can be a bit up and down for quite a while before they level out and you can get on with your life, dont push to hard to often, but do keep it mobile as much as you can is the general idea Im told. Ive got a great cure for low blood pressure, watch Ross Barkley "play" for an hour, mine was recorded heading towards 200/90 last time I did, apparently that makes me clinically dead according to the better half, I said no babe, thats Ross Get well soon.
