Pelvic pain/sciatica? Getting harder to walk

Brittney

I'm going to speak to my Dr about this this week but I'm wondering if anyone is experiencing this. My right side of my pelvis literally feels like it's breaking in half. I have to like drag my right leg when I walk because lifting it to step increases the pain, and then I'm also getting a pain down the back of my right pelvis and into my right hip/leg which I have been told is sciatica. It hurts when I lay down, when I roll over, when I stand. Idk what to do. I've had it for a while and my Dr just told me to use a belly band but there's nothing they can do, which I understand, but I'd like to know WHY it's just that side, and it's concerning how much it effects my walking, etc. Anyone else experience this? I'm 35+2
