In general, if there are no systemic symptoms, you can have sex during the suppuration of a boil on the shoulder; if you have fever, headache and other general discomfort, it is recommended that you do not have sex. Boils, also known as boils, are an acute bacterial suppurative inflammation caused by the invasion of individual hair follicles and surrounding tissues by pathogenic bacteria such as Staphylococcus aureus. The disease is not contagious, and most patients are in the suppurative stage, but the disease is relatively mild, no obvious systemic symptoms, so these patients are usually allowed to have sex. However, there are some patients who have fever, persistent headache, swollen lymph nodes in the neighboring places, and severe pain in the suppurating area on the shoulder, etc. This type of patients is not recommended to have intercourse, because intercourse when there is discomfort in the body may not only reduce the quality of intercourse, but also may not be conducive to the recovery of the disease. For patients in the suppurative stage of boils on the shoulder, it is necessary to go to the dermatology department as soon as possible for treatment.
