Brief Answer:
Developing abscess

Detailed Answer:
Hi.
Thanks for your query and an elucidate history.
Read and understood your concerns.

To recapitulate: male/45 - sore hard lump on testicle (scrotum) - couple of days - has jock's itch not under treatment - purplish sore on the lump - enlarged since yesterday - Benedryl cream - purple is giving away -

You may please post clear photographs for me to understand better as
YYYY@YYYY

From the history your have provided, this looks to be a developing abscess in the pre-existing jock's itch as the skin is already breached for the infection to get an easy entry.

I hope this answer helps you to get a proper diagnosis, and get a proper further treatment. Please feel free to ask for more or if you need further clarifications or if you feel there is a gap of communication.

Brief Answer:
Antibiotic and supportive medicines.

Detailed Answer:
I would suggest you the following:
- First of all apply Liquid Povidone Iodine to the whole area of the scrotum and the thigh all around. This helps to make all the area sterile, kills all the bacteria and avoids the secondary infection. you may do this do twice a day.
- Antibiotic and anti-inflammatory medicines -, you will need a valid prescription of you local Doctor.

- Always clean with plain water and use nothing else and then apply Liquid Povidone Iodine
- Use hair dryer to make the area dry.
- Take multivitamins - helps in good healing and rejuvenating the skin's strength which the scrotal skin looses very fast.
- Loose clothing
- Keep it well ventilated / aerated for fast healing.
- Sterile dressing if required.

I hope this helps you.
