Thanks for your query.Based on the facts that you have posted it appears that you have pain in Rt Testicle. You had sustained injury
to the same Testis one year back .However the pain now can not be related to the injury that you sustained one year back.
This is most likely to be due to infection of the testis or Epididymis
This can be confirmed only on clinical examination .Please consult qualified Urologist
or General Surgeon
for evaluation and further treatment.
You need to take antibiotics and pain killers. Get prescription from your family Physician.
