<s>[INST] Diagnosed with Orchitis. I have an Enlarged and Indurated Left testicle. On Day 4 of Levofloxacin. No Pain...there never has been pain. Just the swelling and induration have been the symptoms. Ultrasound and a physical were taken before the diagnosis was made.However all my research indicates that pain is always associated with Orchitis...was I misdiagnosed? [/INST] HelloThanks for query. You have swelling and induration of Left testis and have done ultrasound scanning of scrotum and been diagnosed to have Orchids. Orchitis is an infection of testicle and is always associated with sever pain and other urinary symptoms like burning urination, fever etc. The other most common cause of swelling of the testicle without pain is Testicular Tumor. You need to consult qualified Urologist for clinical examination to confirm the diagnosis. He may advise for 1)Testicular Biopsy to rule out malignancy of testis 2) MRI of scrotum. Chat Doctor.  </s>
