Twenty two wks, fourth pregnancy, son nearly three, previous mc. Five weeks of terrible pain and three bleeds. They thought it was pelvic girdle pain but now assume it is this thing called round muscle or ligament pain. I thought it was early labour as it was coming and going, could barely move with it on Sunday and worse when I move around z lot. I took codeine but threw up first day back at work. Dr now says codydramol and heat. Is it safe to keep taking this drug. I need two ten in five hundred pills four times a day as wears off after two hours. If I am in pain I can't look after son effectively or go to work. Is there anything else I can do instead of drugs or less mind numbing drugs?
