It could be due to Varicocele
Thanks for your query,based on the facts that you have posted it appears that you have pain in scrotum on Rt side which radiates towards groin.
This could be due to either Varicocele or inflammation of spermatic cord
(Funicullitis) However this can be confirmed only on clinical examination by a qualified General Surgeon
and following basic tests.
1) Routine urine test
2) Ultrasound scanning of scrotum
3) Colour Doppler study of Scrotum.
Please go ahead and consult qualified Urologist and get these tests done under his guidance.In the mean while take broad spectrum antibiotic like Cefexine along with anti inflammatory drug like Diclofenac
Further treatment will depend upon results of these tests and final diagnosis.
Hope I have answered your query ,please feel free to ask if you have more questions ,
I shall be happy to help you
Thanks and Regards.
