Hi,
Noted your history of being diabetic under Insulin and
Metformin and sugar being in range of 125 - 150, got cuts on penis shaft and tried Ivory soap, Summer's Eve, Peroxide, AStor Glide and
Neosporin.
In spite of using so many thing and with
diabetes under control if the cuts have not healed means there is something that is not healing.
This raises the possibility of rare conditions like skin diseases that has affected the shaft of penis like
Lichen Planus and so on.Hence the best way is to consult your Primary and get a reference for a
Dermatologist if required.
Biopsy may be required.
There can be a condition acquired due to use of condoms with local reaction or with lubrication.
STD due to sexual partner suffering from similar problem.
Proper medications after proper diagnosis will help you to get a cure.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant,
