Hi. Thanks for your query, albeit short and specific. Read and understood the history about your Father having the following problems: Enlargement of one testis. Severe pain in the groin area. Gong to bathroom frequently and has chills. I would take this as as a case of severe urinary tract infection with secondary Epididymo-orchitis. I would advise him the following: Send the sample of urine for Culture and sensitivity, routine and microscopy examination before start of any antibiotic to get proper reports. Ultrasonography and color doppler of the abdomen and the scrotum. Tests of blood. Get started with proper antibiotics, anti-inflammatory medicines. Scrotal support. This is the most minimum requirement in spite of not having insurance.
