I know guys won't go to a doctor even if their head were partically cut off, but if the pain is chronic go see a doctor. I just thought my weight, age etc was causing my pain. Turns out I actually have a serious issue (spinal stenosis; arthritis and I will need surgery in time). Good thing about my ailment - cycling helps it. Something about my bent over positioning helps stretch out my back and eases the pain. Sitting bolt upright on a bike will not help but infact, may cause other problems.
Anyway see a doctor and go from there.
