I'm nearly 23 weeks pregnant and have been suffering with pain deep in my right bum cheek since i was about 10 weeks. It's gradually got worse and sometimes if I lean forward at a certain angle I get a sharp pain and find it hard to straighten up and start walking again. I mentioned it to the midwife who I didn't feel was particularly helpful, she said it was sciatica and to take paracetamol for the pain, which i'm not keen to do on a regular basis. Has anyone tried the support belts, or has any experience of whether exercise tends to make it better or worse?
