My question: I use to be a body builder when I was younger, I was doing some stretching right before I was going to workout and there was a popping sound in my lower groin. Before the popping sound injury, I was able to have a erection very firmly, as soon as that happened, I could not. This happened when I was 26 and I am 44 now. I have been through test after test with doctors of trying to find out the problem. So ever since then, I have not been able to maintain a erection or be able to keep any blood flow. I have become very frustrated with this situation to where it seems that no doctor has a answer. All the test come up negative but I have such pain in the lower area now and can't understand why one day I can be firm and then the next, nothing. It is like a light switch, on and off when it did happen. I would appreciate it if you could help me on this matter so that I can talk to my docs to see if this can be resolve. When this popped, I was thinking that it was a tendon or a muscle. Made the same sound when I snapped my achillies tendon. Thank you from CA
