Stem overgrowth does not recover on its own. Excessive penile protuberance is referred to as penile protuberance syndrome. If the length of penile protuberance is more than 2.5 cm, it can be judged as penile protuberance syndrome, which may have symptoms such as sore throat, foreign body sensation in the throat, earache, etc. It can’t be recovered on its own, and it is necessary to take anti-inflammatory and pain-relieving medicines under the guidance of a professional doctor, such as indomethacin, and it can be assisted with physical therapy, such as infrared ray and ultra-short-wave irradiation to alleviate the symptoms. If Stem Syndrome is more serious, a reasonable surgical treatment plan should be formulated in conjunction with the professional doctor’s treatment recommendations. Common surgical methods include trans-oral pharyngeal route to cut off the stenosis, trans-cervical route to cut off the stenosis, etc. At the same time, it is also necessary to cooperate with the application of antibiotic drugs, such as cephalosporin, penicillin, etc., to carry out postoperative adjuvant therapy to promote recovery. If you have stenosis syndrome, it is recommended to cooperate with professional doctors for standardized treatment as soon as possible. Diet should be light and avoid spicy and stimulating food.
