Does anyone have it? I'm nearly 24 weeks and it seems to be getting worse and worse. Last night I only managed half hour sleep

I phoned the hospital and spoke to a midwife there and she said they only person who can help me is my gp... I saw him about this problem at 18 weeks and he basically told me "its part of pregnancy, you just have to deal with it and put up with it".
I don't see my midwife at the gp now until the 28th, and can't have any more time of work.
My job involves sitting down at a desk all day... with various trips up and down stairs to the loo. Then its a half hour walk to work in a morning, then a half hour walk back.
We move house on the 26th so I'm desperately trying to get a tiny bit of packing done each day... but its so hard as bending, lifting, sitting, standing, twisting... well everything I do really... makes the pain worse.
I can no longer get comfy in bed no matter what I do!! It's driving me mad I want to enjoy my pregnancy

Any advice or anyone reassure me its not just me going throught this? x
