Right side pain 22 weeks

I'm 22 weeks pregnant and I'm having HORRIBLE pain in my right side. Like more towards the back. It's like where my kidney is. It hurts so bad that I can't move and I want to cry. What should I do? Should I go to L&D;? They won't take me in the ER because I'm past 20 weeks. It hurts so bad and idk if it's normal, if it's something I shouldn't worry about. Anyone else have this or had this???? Advice please!
