I've got a bad lower back since 2009 main issue is the sacroiliac joint on left hand side..it was made worse by pregnancy in 2011 and now 22 weeks pregnant with dc2. My lower left back has been niggling but over the past few days I now have pain and stiffness across the whole of my lower back, pain in my hips and pubic bone. Walking too far gives me sharp pains and I cannot get comfy sitting, standing or sleeping.... Physio (f) says to try a pelvic support belt, but can't help more as I can't do the excercises without making my back worse...chiropractor (m) says not to get a belt and just stretch out my back when I can....I am confused as to what to do, at this point will try anything to ease discomfort.....can anyone help with any advice re back/pelvis pain in pregnancy? feel like such an old lady...help!!
