Unbearable back pain

I'm currently 29 weeks and 2 days I had my boyfriend pop my back cause I thought it would make it feel better but it has made it much more worse. 😓 My back is killing me whether I'm laying down or standing it continuously hurts especially walking it makes it so hard. My head also hurts like I have a fever going on and I will get nauseous. I don't know what I can to relieve the pain I need help I've been in pain for going on three days straight.  😓😭
