question: Hello To who ever can help me answer my question Please and I really appreciate your help, I hurt my back last year on March, Got my Mri done and was told I had two bulging disk L4 L5, so after they gave me a cortisone shot on September notice I started to lack to have an erection but didn't put to much of attention since I was still enjoying good sexit with my girlfriend.I just had a second shot on Monday of this week and now I'm definitely notice that I could have a problem with erection dysfunction, Im really scared , I wanted to know if the injection could be the cause of it and if so How long do you think it will last.? Thanks again.
