Pregnancy= Severe Pain

I am currently 29 weeks and experiencing very severe sciatica pain mixed with a very severe sharp pain that runs down my hip and wraps around in my groin and inner thigh down my leg. Has anyone else experienced this too? What did you do to help with the pain? I am currently on Tylenol around the clock and I am not feeling much alleviation. I can't walk and can barely move my leg around.
