I'm 24 week pg and already have a huge bump. It's causing me to have the worst back ache ever. Iv been in bed all day due to being really poorly and just not really being able to move. Iv had a hot water bottle on it for the past hour and had some paracetamol and the pain is still so bad. Seems to be getting worse every day. An ideas on what else I can do to ease the pain? Tia
