I had it in lockdown originally (before babies) and i found sitting was the worst part. As you recover and get back to moving fully like before it may die down. Mine did when I got back to walking a lot. I had stretches from Dr given to me. Once I had my section, when I recovered from that and began moving my sciatica also chilled out and went. Started with it again this time at 8 weeks so ready for it to go again too!
Have you tried Accupunture? Weekly sessions for a while really helped me
I suffer with sciatica, a strong ibuprofen helps. 600mg. Works best before bed. Sometimes I take 2 tabs. As its a inflamed nerve. Ibuprofen takes inflammation away
