help!

for the past 3 days I have been limping the back side of my lower back makes me walk that way, it's not horrible pain, I can't exactly describe it. I just can't walk right , it hurts. I think he is on my sciatic nerve. what can I do about this ?

also, sorry tmi but 2 days ago and last night I felt so nausea and threw up, what's going on there? I heard it can mean labor is about to come.
