I ve been having continuous left side lower back pain. Half the time my lower back gets tight. Every morning I feel severe lower pain . However, throughout the day I can function normally but with pain. I have already taken naproxen but that helped alittle. What should I do, should I put ice or heat on my back. Please note, when I make a fist and place it at the base of my back and press it inward while arching my back I do get a momentary relieve from the pain. In addition, I had a sciatica injury on my left side and I have a damage to my L5 & L6 and another part of my spine. I am a athlete and a weightlifter. So, what is wrong with me.
