In men, the main symptom is abnormalities in the genitourinary tract. Pain when urinating, medically called painful urination, is the main manifestation of inflammation of the urethra, which can be burning pain, burning pain, burning sensation, and the degree of pain varies from person to person, some are mild, some are severe, this condition mainly occurs in gonorrhea and chlamydia genital tract infection. Frequent and urgent urination is also a symptom of both diseases and an irritant symptom of inflammation of the urethra. Frequent urination means that you always have the urge to urinate, and you want to urinate after you have just done so. Urinary urgency even when the urge to urinate hurriedly have to urinate, otherwise you have to urinate pants, it is difficult to control urination, these are symptoms of urethritis and urethral irritation, if you can combine with a history of unclean sexual contact, there is a possibility of sexually transmitted diseases. Urethral overflow is a common symptom of acute gonorrhea and is the main basis for the diagnosis of gonorrhea. Overflowing urine is the loss of control over urination due to incomplete closure of the sphincter of urination caused by inflammation, injury or scar formation in the urethra, seen in the acute and chronic phases of gonorrhea and chlamydial or mycoplasma-infected urethritis. The actual fact is that some people, especially young people, have an erection for different reasons or in the morning, an erection that lasts a little longer and then returns to normal and soft, when there is some clear mucus flowing out of the urethra, which is the secretion of the prostate gland, which is normal and not a pathology, do not confuse this phenomenon with a sexually transmitted disease. The symptoms of syphilis include nodules, ulcers and inflammation in the male genital area, including the foreskin, glans and urethra, which are symptoms of the hard or soft chancre of stage 1 syphilis; herpes genitalis, which appears as a cluster of small blisters or vesicles and shallow ulcers; flat warts in the above-mentioned areas of stage 2 syphilis; warts in the above-mentioned areas of patients with condyloma acuminata, especially on the foreskin, coronal sulcus and glans, and sometimes on the urethra, which become more and more numerous and larger. increasingly large and contagious. 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. The doctor treated by acromegaly, causing great pain to themselves. The lice disease is lice in the pubic hair area, due to the bite of lice, can grow many inflammatory papules in the pubic hair area, which is what we call a lot of itchy bumps. By the way, we tell you that there are generally three kinds of lice, one growing on the human body called body lice, the second growing on the head called head lice, the third growing on the pubic hair called pubic lice, we note that these three kinds of lice do not mix, body lice do not appear on the pubic hair, pubic lice on the pubic hair will not grow to the body and head. Some patients for this matter single looking for me to register for advice, fearing that their pubic lice will spread to members of the family and grow a body full of lice, which will not. But pubic lice occasionally occur in the patient’s armpit hair, eyebrows this is also very rare. Scabies is also a common highly contagious sexually transmitted disease, scabies in the male foreskin, glans occurs a kind of itchy nodules, long-term, this scabies nodules when the patient’s body other places scabies have disappeared, scabies nodules in the pubic area still need to be treated for a period of time. There are also swollen lymph nodes and ulcers in the groin, which in common parlance means swollen bumps at the base of the thighs. The bumps of syphilis are swollen and hard, painless and do not break down. The lymph nodes in soft chancre can form abscesses and ulcers, and in venereal lymphogranuloma and inguinal granuloma, inguinal lymph nodes can form abscesses, ulcers and fistulas. These are generally no longer early symptoms of STDs, but rather late manifestations of STDs. These are the symptoms that can be associated with STDs in men. The following point I also want to say: the symptoms of STDs can not only appear in the male and female genital organs, some other non-genital organs damage may also be STDs, for example: 1, oral cavity, throat damage (related to oral sex): syphilis in the lips, oral cavity or throat hard chancre can be shallow ulcers, oral mucosa second stage syphilis spot, papular syphilis rash, and even late stage gum nodules; gonococcal stomatitis and gonorrhea pharyngitis (flushed and congested with purulent discharge), Candida albicans stomatitis (buccal mucosa and tongue). 2. Anal: pain during defecation, rectal swelling, blood and pus in the stool may be gonorrheal proctitis (mainly seen in anal sex), perianal ulcers may be hard chancre of syphilis, perianal bumps may be condyloma acuminata or flat warts of stage II syphilis, itchy red spots around the anus may be Candida infection or scabies, etc. 3, brain damage: in syphilis, phase II syphilis and phase III syphilis can have neurological damage, like meningitis, cerebrovascular disease, paralytic dementia, spinal consumption, etc.; AIDS has neurological symptoms of up to 30% to 70%, which can be manifested as dizziness, headache, epilepsy, progressive dementia, cerebral neuritis, ataxia and even paralysis, etc. 4, cardiovascular damage: cardiovascular syphilis is an important manifestation of advanced syphilis, including aortitis, aortic aneurysm, aortic valve atresia, coronary artery mouth stenosis or atresia, myocardial dendritic swelling, these damages are destructive, harmful and have a high mortality rate, like aortic aneurysm if it suddenly ruptures, which can lead to sudden death of the patient. 5, digestive tract: Phase II syphilis can have hepatosplenomegaly, and gonorrheal sepsis can occur in acute hepatitis. 6. Bone and joint involvement: disseminated gonorrhea (gonococcus invades the blood from the mucosal infection site and causes a serious systemic infection through hematogenous dissemination), including gonorrheal arthritis, synovitis and tenosynovitis in the knee, elbow, wrist, ankle and shoulder joints, and congestion and swelling of the joints, which can lead to joint fibrosis and ankylosis if left untreated. In addition to gonorrhea, syphilis also has bone and joint damage. Periostitis, osteitis, arthritis, synovitis, and tenosynovitis in stage II syphilis, and bone damage in late stage syphilis with osteochondritis are common.
