SPD/PGP

So I've just rang in work sick because I have seen every single hour of tonight in pain and struggling to walk to the 5 bathroom trips ive had to make to wee. There is no way I can complete a 12.5 hour shift constantly on my feet on a hospital ward like this. It makes me so frustrated because I'm in the middle of working the weeks were my maternity pay is calculated. It seems this baby is determined to make me poor for when I actually get the time off to try and enjoy the last part of this pregnancy. I have some physio on the 25th but I need solutions/relief like NOW! My hips and groin feel like they are in a vice that is constantly being cranked up while 2 body builders are trying to pull my legs off my body. I've resorted to taking some pain relief, only paracetamol which probably won't even do anything but I'm desperate.
