I’m broken 😭

For the last week and a half I have been suffering from terrible hip/ back pain. It’s so hard to pinpoint exactly where it’s coming from but it’s that general area. This is occurring on my left side. It originally started off as a soreness and then we traveled 9+ hours out of town for a work trip/ mini vacation. Since being here my pain has become excruciating. I can barley walk, anytime I apply any weight or pressure to my left side I buckle and fall. It’s a very sharp constant pain. I’ve been staying active In hopes that it would work itself out. I have resorted to a limp just so I can continue my daily life and not be a peak on this trip. At night I take a warm bath, apply a heating pad and use a natural icy hot spray. When I lay down I can’t even lay stray or put my left leg flat without it feeling like I broke it. I have no idea what is going on and I see no relief in sight. I am 17 weeks pregnant and was told this is sciatic pain but I’m not too sure now.
