Problems with male reproductive organs

Patient's question:

Patient Gender: Male
Patient Age: 35
I don’t have foreskin and I’m not sure if it’s from athlete’s foot or poor hygiene during masturbation. The glans is red and swollen, and there are small red bumps around the coronal sulcus. I bought potassium permanganate powder but don’t know how to mix it and don’t dare to use it rashly. I also bought metronidazole sustained-release tablets.

Doctor's answer:

Health advisor answers for you: Regarding balanitis, if you want to use potassium permanganate for washing, how should the concentration be prepared? Based on the situation you described, it should be considered that balanitis has caused redness and swelling in the coronal sulcus. You can rinse with clean water or use potassium permanganate for washing. Generally, the use of potassium permanganate must not have a too high concentration, otherwise it may burn the tissues.
Advice: For the preparation of potassium permanganate, you can put a few grains of potassium permanganate into the water, and the concentration is just when the water turns slightly colored. If the color is too deep, it means the concentration is too high. Regarding your situation, I believe it may not be necessary to use medication, meaning no medication should be taken. Cleaning can solve the problem. In the future, you can just rinse with clean water regularly.
