I hope you don't have to have to surgery bro. I am not sure what to tell you, but I can relate an experience I had 9 years ago in my freshman year of college.
I was doing leg presses on a fixed seat leg press machine (meaning you couldn't adjust the seat angle) on each rep in order to get my legs to the parallel point, I had to lift my butt up off the seat and let my lower back round itself off a little bit in order to get the weight down. Well by the third set, I was feeling a tight stretch and strain in my lower back. The next set afterwards, I stood up and my back POPPED. I got hot in the face and threw up on the floor and had to sit down. I felt feverish but was clammy cold. I had to sit in the locker room about 15 minutes just to stop shaking (like going into low blood sugar state).
I went home and the next morning, I could not get out of bed. I mean, if the dorm would have been on fire, I would not have been able to get up on my own. Two hours later my dorm buddy came to find me and when he went to pull me up by the arms, I passed out. After coming too, and for two weeks after that, the only way I could get out of bed was to lay flat and throw my legs over the side and slowly slide myself off the bed until my knees touched the floor and stand up. It would take my breath away. I could not go to the bathroom and sit down to crap without taking over 20 minutes just getting down in the sitting position and having tears in my eyes. I couldn't sit in a chair that was normal height, I had to use a bar stool for classes so I could just slide off and land on my feet.
I was scared shitless, mainly because my father had 6 back operations in his lifetime and each time, they caused more problems than they cured.
In the end, it was about 8 months later, after a lot of heavy massages that I had the ability to move around freely as I did before with no pain. Though, I was very limited in what I could do in the gym, I was not able to return to some of the basic exercises (squats, rows, overhead shoulder presses, leg presses, etc..) for another two years. I never went to the doctor because I had no insurance and my family could not afford to send me money to see the doctor with. So I don't know what the cause of it was.
After college, I was recovered to 85% before with my strength gains and exercise ability. After I got my first job and had health insurance, I went to the doctor and can you believe that he could not find anything wrong with me? Even after mulitple Xrays.
So maybe you just strained a muscle or something. Check into getting a hard therapetic massage twice weekly (insurance will cover, otherwise it is about $40).
