Go see a doctor...but fwiw I have the same issue a long time ago because all of my exercise during my weight loss journey was forward motion related. I started adding exercises that stressed side to side movement a did a ton of stretching of the hip flexors. I also started lifting instead of just doing cardio. And stopped keeping my wallet in my pocket while driving or sitting at work. I guess you could say I took the shotgun approach to easing sciatica, but I haven't had problems in a couple of years!
