I agree with skidaddle motherofz. You really don't want to wait. I am sure your GP will be more helpful.
Don't anyone assume that it will be ok to struggle on and that it will be ok after the birth. My colleague (another physio) started using crutches at 23 weeks and had to use them for a year after she gave birth. This is obviously not inevitable, but please take it seriously and insist on a referral to a women's health physio.
Caz, I have to admit that may seems a long way away! Maybe it is because it is my first. I am comforting myself that I will be doing 3 days per week and 8 hours per day, rather than the 60 hours per week it has taken to set up my business. October 24th cannot come soon enough, though- getting really tired now.
Had to rush over to someone's office today and treat their neck on a low bench, after i had lifted the bench. She felt miles better after, but I did have my doubts about myself! not wise to play russian roulette with one's own body when not PG, never mind now!
