Question: I'm 23, 5' 10", and have no significant medical history. Within the past couple months, I have had two bouts with a gastroenteritis-type bug, one of which ended with a rash. The rash was primarily around my thighs and waistline but eventually spread to my extremities and lasted about one night. Now, about 10 days later after the second bout, my penis feels numb and warm to the touch. It feels foreign, almost like dead weight. I can't develop a full erection and there seems to be a huge loss of sensation. No penile injuries that I'm aware of. Normal sex and masturbation habits. I haven't had sex in almost two months. I should also mention that I've tested negative for all STD's. I'm also experiencing fatigue, back pain, and somewhat enlarged lymph nodes in the neck. But I'm not sure if these are related or byproducts of the stress or what.

I have convinced myself I have everything from Guillan-Barre to prostatitis to varicocele to MS to Lyme's and I'm just scared to my wit's end. I would appreciate any guidance. I'm not even sure if I should visit a urologist or a neurologist or God only knows... Thank you.

What about the abrupt numbness? I'm also developing a suspicion that incomplete bowel movements could be related but I can't decide if I'm just throwing any possibly symptom into the mix here. But what disease do you think this could plausibly be?
