###Human: What treatment is advised for post-ejaculation muscle spasms and nerve irritation? ###Assistant: Hi. I have gone through your query and the images that you have sent (attachment removed to protect patient identity). There is definitely a curvature that is appreciated on the images, but I cannot confirm whether it is Peyronie's disease without actually examining you myself. It is however among the few possibilities that can cause your present condition. I would like to know a few more details about the last time you masturbated. Did you find any sudden loss of erection or swelling of the penis after ejaculation? Did you feel a popping sensation in your penis at that time? Immediately after did you have any partial erections, and were these erections painful?  The usual cause of this type of problem is a tiny injury to the layers covering the penis which give it stiffness. This could also explain why you did not have erections for sometime immediately after. The important thing is to rule out Peyronie's disease which can be progressive, the others are not. If it is just a curvature, without Peyronie's, it is necessary to check whether you are able to have normal erections, from the images it does appear that your erections are normal (needs to be confirmed during an examination). If it does not interfere with penetration, then usually we do not intervene unless the patient specifically requests for cosmetic purposes. So, to summarize, it is not likely to be Peyronie's, but I would definitely want to rule out with an examination and maybe an ultrasound if necessary. Such a slight curvature would usually not require any further treatment unless it interferes with penetrative intercourse.
