Thanks for your query,based on the facts that you have posted it appears that you have swelling in both the testicles .This could be due to infection of the Epididymis
However this needs to be confirmed by clinical examination by a qualified General Surgeon
and ultrasound scanning of the scrotum.
You need to take broad spectrum antibiotic like Cefexine along with anti inflammatory drug like Diclofenac
Further treatment will be decided by him and depends on final diagnosis,
