Maternity support??

I’m almost 31 weeks pregnant and have horrible sciatic pain since the last 2-3 months. Anybody know of any good maternity support belt or maternity tights that can help with the pain. I. An barely stand or walk. And it just gets worst during the day. I’m going to the chiropractor twice or thrice a week but still in pain because of the sciatic nerve.

Anyone going through this and what are y’all doing to kind of ease out the pain. I know it won’t completely go away but atleast I can find some comfort.
