Have had lower back pain, off and on for years. I am 47 years old and recently (in about the last three months it changed, some times worse as I sleep, some times wakes me up, before rest always made it better. I am a electrician-maintenance man, 9-5 Mon -Fri and am generally rested on Sat and Sun. Mon -Fri I wake up early and walk on a treadmill, and stretch, this does help. I do not know if connected but my left testicle has experienced some discomfort during this time, no swelling or bleeding, and not all-the-time. Testicle thing seems about gone. Ed
