Back pain while erection

Patient: My friend age is 40 years and he is in a condition where whenever he gets an erection he gets extreme lower back pain. This has been going on for a few years and he goes to the chiropractor every week but the relief is only temporary. He’s also gone to specialists who just look at him wierd when he tells them what his problem is. So my question is what should he do?? What could be the problem causing him all of this pain??? Does anyone else have the same problem and how do you deal with it???Read more: http://www.healthboards.com/boards/back-problems/330601-erections-cause-back-pain.html#ixzz3PQlfJsR4
