Epididymitis is a common disease in the male genital area, which is usually caused by the spread of infection from neighboring organs. Acute epididymitis is characterized by sudden pain in the scrotal area, rapid swelling of the epididymis, obvious tenderness, and fever. If the treatment is not complete in the acute stage, it will turn into chronic epididymitis, which is characterized by hard nodules in the epididymis and may be accompanied by scrotal cramps, swelling and pain, and abdominal urgency. The testicular infection and epididymitis are mostly caused by infections such as mumps, typhoid, influenza, urethritis, prostatitis, etc. There are two types of acute and chronic. The inflammation of the testicles and epididymis are called orchitis and epididymitis respectively, which is the difference between orchitis and epididymitis. Because of their closely related anatomical locations, they often occur in conjunction with each other. The most common cause of acute epididymitis is infection by Brucella canis. Some mycoses, such as bacteriophage and coccidioidomycosis, can cause granulomatous orchitis and epididymitis. Trauma to the testes and epididymis can sometimes cause inflammation and infection. The difference between acute and chronic epididymitis is 1. The symptoms of acute epididymitis are: sudden high fever, elevated white blood cells, scrotal swelling and pain on the affected side, sinking sensation, pulling pain in the lower abdomen and groin, and intensifying when standing or walking. The epididymis on the affected side is enlarged and there is obvious pressure pain. When the inflammation is large, both the epididymis and the testicle are swollen, and the boundary between them is indistinct to the touch, which is called epididymitis orchitis. The spermatic cord on the affected side is thickened and there is also tenderness. In general, the acute symptoms can gradually subside after a week. The patient often feels a vague pain in the affected scrotum, a feeling of swelling, and the pain often involves the lower abdomen and the ipsilateral groin, sometimes combined with secondary syringomyelia. On examination, the epididymis is often enlarged and hardened to varying degrees. There is mild pressure pain, and the ipsilateral vas deferens can be thickened. Therefore, the traditional treatment of epididymitis is mainly based on the use of antimicrobials, painkillers and surgical drainage, which usually only relieve the temporary pain, treat the symptoms but not the root cause, the effect can not last, and long-term use, will make the pathogenic bacteria resistant to drugs, and the side effects are also large. The actual fact is that you can find a lot of people who are not able to get a good deal on this kind of things. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. This is the reason that urethritis, prostatitis and vesiculitis are all possible causes of epididymitis. 2. Bloodstream infection: Inflammation caused by pathogens from other parts of the body reaching the testicles and epididymis through the blood circulation system. The actual fact is that you can find a lot of bacteria in your bloodstream, such as tuberculosis, kidney tuberculosis, and abscesses in your body, which can also cause epididymitis through bloodstream infections. 3, lymphatic infection: through the lymphatic reflux of the lymphatic system, bacteria along the lymphatic vessels to the testes epididymis caused by the infection. 4, local infection: If there is an inflammatory infection in the perineum, such as the scrotum, it may also spread directly to the testicle epididymis.
