Pregnancy sciatica

I've been suffering with sciatica since around week 15 of this pregnancy. I've never had this before (pre pregnancy) so wasn't able to diagnose the pain for the first 5 weeks. I just thought it was my pelvis changing during pregnancy 🙈😂

At first it wasn't too bad, just little aches & sharp pains every now & again but it's become very painfull over the last 2 weeks - to a point where I want to cry when I feel it flaring up. Does anyone have any tips, tricks or home remedies to reduce pain or get rid of this altogether?

I'm becoming desperate, at just 25 weeks now - I don't know how much worse this will get but I'm already broken by it 😫😫
