Painful hypersensitivity of glans. Know.

I underwent circumcision using a ZSR stapler on Monday morning, and a bandage was applied until today. My doctor asked me to remove the bandage with warm water and apply T-Bact. However, when I removed it, I experienced extreme pain due to hypersensitivity, which made me scream. The pain is unbearable, and applying T-Bact was beyond painful. I haven’t slept for 72 hours due to the hypersensitivity and am concerned since I have college next week. My doctor denies the concept of  hypersensitivity and hasn’t been helpful. I need advice on how to treat it, protect the area from touching anything, and whether there’s any ointment or liquid solution gentler than T-Bact or petroleum jelly. I’m in severe pain and sleep-deprived. If there are any homeopathic or alternative remedies, please let me know.
