I recently have posted I regained full penile sensation after dropping minox. My timeline is I had scalp ringworm, dropped minox and went on the potent anti fungal Terbinafine. Two weeks later, my penis was completely normal.
It now seems to be numb again but I think a little better than before. I have been off Terbinafine for a while so now it seems like the Terbinafine was the cause of the improvements.
I was so happy and thought it was all the minox but I guess not but maybe i need to go down the anti fungal path.
