I am currently 30 weeks pregnant and have been suffering for 3 weeks with the most severe middle back pain. I have tried EVERYTHING to fix it you name it physio, osteo, acupuncture, pain killers, ice, heat... you get the idea. I could not sleep I was in so much pain and GP/midwife not interested just suggested exercises which I was doing religiously before the pain and continued through it... well yesterday in a last ditch attempt I had some cupping and omg it's worked. If you have a practitioner near you who's happy to offer cupping in pregnancy please please give it a go!
