I’m pregnant and have a 3 year old toddler. My sciatica pain is so bad that I haven’t been able to get out of bed for over a week now. I feel so bad because I can’t do anything with my son so we literally lay in bed all day watching TV. He is so over stimulated and he keeps misbehaving bevause of it . and I really just don’t know what to do 
You need to stretch and talk to your doctor about physical therapy laying in bed won’t do ya any good ya need to work it out girl I have had it since my first pregnancy 13 almost 14 years ago and it will even about drop me sometimes but stretching your hips and heating bad and ice but mostly stretching look up sciatica stretches
You’ll need to go see a physio if its that bad hun. I’d also suggest a standing walking frame to help stabilise you a little while you’re struggling with this. But def see a doctor. Don’t take random advice from the internet. Spine health is so important and being pregnant too you don’t want to make it any worse.
