I have complete sympathy with you. i didn't have any pain relief when i had my child, but through one acid or another i have had loads of problems. and now suffer from a spine of a ninety yr old.
There s good news though, I had acupunture it was fantastic, i then did quite a lot of core support exercise. after 4 years of hell, i am now completely pain free. i don't go overboard. i do live a very active life and i can keep up with my 10 year old.
Good luck! don't give up you'll be ok! i'd be more scared of tennor lady than back pain! don't buy a trampoline, even though they're half price in argos.
LoL
