I've started getting spasms in my back. Not my whole back at the sametime but in sections so sometimes in my neck sometimes in my lower back etc. Feels like sciatica its awful. Could baby be laying on a nerve to cause this? I have ongoing back pain and scatica in my leg anyway (had it pre preg) and i've got physio on 5th March but it feels so far away! Anyone else have the same trouble?
