Thanks for the consult...
It might be due to fungal infection
1. I read your query. I am happy to help you. You said that you have hard skin bruise
and pain near the right testicle
2. This might be due to fungal infection.
3. Use Ointment cotrimazole for local application and tab.fluconazole
120mg twice a day for 5 days
4. The test that you have to do is the collection of bruise at the site of infection and send it to laboratory for culture
Hope this information helps...
