I just recently had a Bilateral Lumbar Facet joint injection this past Monday and I regret it because I think im experiencing erectile dysfunction because of it, I was great last week enjoying good sex with her and now Im scarred of how long can this last? Has anybody experience the same problem if so How long did it last?? Well I should of started by saying I injured my back , disc L4,L5, L5-S1 and so I had one cortisone shot too. Thankyou for your time and hope someone can answer my question.
