Sciatica

Holly • Pregnant with second child following two miscarriages.
I'm 35 weeks pregnant and just been diognosed with sciatica in my left leg. It's so painful I can't do anything, walking is so painful, I can't bend down to pick things up or get out of a chair or bed easily. I've got a 1 year old at home who I can now no longer pick up or look after without some help. Anyone else experienced this?
