SPD in pregnancy sucks!

Currently sat on my ball looking like something out of shrek as SPD has had me up most of the night in agony, hospital was supposed to reffer me to physio this was almosy 5 weeks ago! I cant hace any cocodomol as i hace an allergy to the condine, paracetomol is useless for the pain, tried pillow invetween my legs at night this for me makes the pain worse, the only thing that seems to help is a hot bath which lets face it i cant just lie in a bath 24/7, 3 and a half weeks to go and counting!
