My test become hard after doppler ultrasound test found, epididymitis infection it having 8 month or more but hardness remains same. Give some suggest?

Recheck. Recommend you again visit your urologist for another exam. If needed, ultrasound can be repeated. Persistent scrotal "hardness" is not common after treatment of bacterial epididymitis. Testicular cancer and uncommon infections, such as tuberculosis, need to considered.
