Help! Back pain

I am having horrible back pain. It’s like middle/lower side pain. It’s constant and nonstop. To the point where I’m crying off and on. I’m also having cramps/tightening but it’s not so often. Maybe ever 20-30 mins for like 10 seconds. Omg now can I help this? I took a hot bath, heating pad, Tylenol, propped up pillows. My husband massages me. I feel horrible and I don’t want to go to hospital for them to basically say it’s normal and send me right home.
