The testes and epididymis are called the sacred sons of the testes and epididymis, so inflammation in these two locations is called canker sores. In clinical practice, there are acute and chronic canker sores, characterized by painful swelling of the testes and epididymis, which is equivalent to acute and chronic epididymitis or orchitis in Western medicine. When acute canker sores develop, the testicles or epididymis will be swollen and painful, and the onset of pain is usually sudden and varies in intensity, increasing when moving or standing. If the scrotum is red and swollen, the scrotum will be swollen and fluctuating after the pus is broken or drained, the symptoms will subside and the wound will heal quickly. The patient may have a history of acute canker sores and may have had acute canker sores in the past. During the examination, the testicles or epididymis may be enlarged and have mild pressure pain, and the vas deferens may be thickened. Blood test. The blood count of acute canker sores may be increased, and there may be white blood cells in the urine, so it is important to consider the possibility of epididymal tuberculosis when identifying it.
