I got epidydmo orchitis almost one month I went to see doctor several times and did three times ultrosound tests and blood tests and urine tests all these results showed good and the doctor have no idea what to do I took antibiotics for nearly four weeks

See urologist. Common causes of epididymo-orchitis are infections with bacteria, chlamydia and viruses (like mumps virus). Trauma is another cause. Sometimes the underlying infection is in the prostate. Chronic prostatitis can present as testicular pain. These conditions are treated with antibiotics and non-steroidal anti inflammatory drugs. I suggest you see a urologist at this stage.
