Thanks for your query,based on the facts that you have posted it appears that you have developed Bilateral Epididymitis
You had epididymitis on one side and you have taken aantiiotics for the same.
Epididymitis takes long time (4-6 weeks) to recover and ihat is the reason the infection has spread to opposite side.
Take antibiotics like Doxycycline along wih anti inflammatory medicine like Diclofenac
and serripeptidase twice daily for a month
it should get cured.
