I had SPD v badly during my pregnancy with ds2, and after he was born, had problems with my right leg (could not lift it, had to sort of drag it around behind me, and continue to use crutches for a couple of weeks until the feeling came back). This all cleared up, although I always have to sleep with a pillow between my legs, otherwise my hips hurt.
A couple of days ago, I started to get problems at the top of my right leg again, and it's now quite bad, can't move the leg forward without a lot of pain at the top - v similar to how it was after ds2.
Can't get to the doctor today because of it - will have to wait until dh is around to get me there.
I'm wondering if it is to do with the SPD - anyone else have similar problems?
