Lower Left Back Pain!!!!

Doctor says it's just sciatica during pregnancy but nothing is helping! 26 Weeks and I feel like I have a pinched nerve. I randomly get sharp pains in my lower left back, down my butt, then into my legs. Not to mention my thighs are always buring and I feel like my hips are widening. Just want a tad bit of relief for these next 3 months😔 I've been using a heating pad. Taking Tylenol. I'm all out of opinions. Doctor said it would ease up on its own but I'm not sure she's felt it and understands it's quite painful to just do nothing about!!!! Has anyone had the same thing? If so, what helped😔😔😔
