ADVICE....almost 31 weeks all over pain😩

So lately I haven’t been able to sleep due to when I lay down both my legs get hot and then they tingle and then they feel like they fell asleep. It doesn’t matter how many times I move it just does it constantly. Now I’m having upper belly pain like right under the boobs and it goes across. It doesn’t feel like anything on the inside but when I walk even slightly from one room to another it gets super tight and shoot the pain across. I have sciatica really bad and that pain will shoot from my back and feel like it’s going into my stomach. My doctor doesn’t seem to concerned but it’s just so odd to have all these problems. Anyone else the same? 😭😭😭
