thank you so much for replying mrsd! iv read some articles on how pentox helps with nerve damage plus softening and dissolving scar tissue.

i have some questions
is there vasa nervorum in the penis? like the blood vessels that supply blood and oxygen to the peripheral nerves? ever since i squeezed my penis losing my sensitivity, its been discolored like it isnt getting any fresh blood. almost like a shaded black, but it used to be very bright and yellow. so im thinking if the vasa vervnoum are compressed from the scar tissue and if the nerves arnt getting alot of fresh blood, mild ischemia can occur, right? which is causing my mild discoloration along with the numbness?

this is where i hope pentoxifylline might help, because the pentoxifylline makes the red blood cells flexible so they can squeeze in through the vasa nervorum and get blood and oxygen into the nerves.

i have another question, nerve injuries gradually heal right? but mine didnt, the sensation spontaneously returned after a session of masturbation and then i squeezed it again because i freaked out because i was ejaculating but not orgasming, which is the dumbest thing...i know i reminded how dumb it was everyday. are the nerve injuries that usually spontaneously return are those the injuries where a nerve is compressed and uncompresses itself?

iv also been taking b12, and i also went to the neurologist who looked at my dorsal nerves from the mri and told me everything looked fine, but how can it be when im this numb and i cant even feel my penis or feel my urethra when i pee.
i asked him if i could get a emg, but he said he dosent think it will help much and he dosent know much about that. so know i feel utterly helpless and dont know what to do. should i go to a urogloist who specializes in neurogenic dysfunction or should i go another neurologist and try to get an emg for the penis?

iv already been to my urologist who thinks i should go to a neurologist.
