It's 1 am and I'm having an issue!!!

It's 1:00 am where I live right now. I went to get into bed at 10 but I haven't fallen asleep once. I'm on birth control but I also let my boyfriend cum in me 2-3 times a week. I keep getting a chilled feeling on the inside of my whole back. It starts at the bottom and goes up from there. It's a little painful but more uncomfortable than anything. I have to keep moving around. If I lay down it keep doing the chilled feeling. It feels like it's locking up my back and it hurts a little after. Every once in a while it has a slight pressure, pinching pain, or tingle. I can't sleep and I don't know what to do. I've tried laying in every position and nothing is working. Does anyone have any idea why this happening?!?
Someone please comment. I'm so desperate right now. I'm so tired but I can't sleep because of this!!
