Brief Answer:
Fungal infections likely,

Detailed Answer:
thank you for asking
painful burning sensation with the rash and swollen scrotum needs a little work up. It sounds like an infection and fungal odds are more likely. Hygiene needs to be addressed here and modifications of hygiene and coital habits are necessary. Tinea cruris and candidiasis are the likely possibilities. a tropical climate, wearing tight-fitting clothes (including bathing suits) for extended periods, sharing clothing with others, participating in sports, or coexisting diabetes mellitus or obesity. Prison inmates, members of the armed forces, members of athletic teams, and people who wear tight clothing may be subject to independent or additional risk for dermatophytosis.
Nutshell, you need some antifungal medications and a consult to a dermatologist for further management.

I hope it helps . Take good care of yourself and dont forget to close the discussion please.
May the odds be ever in your favour.
