Paraffin oil is generally not useful when the glans is sensitive. Patients with symptoms of glans sensitivity may be related to prostatitis, glans inflammation, phimosis, prepuce, etc. At this time, applying paraffin oil will generally not play a desensitizing effect. Patients need to take different treatment measures according to different situations. If caused by prostatitis, glans, etc., it is best to do bacterial culture and drug sensitivity test to determine the appropriate antibiotic, before the above results come out can also be empirically applied levofloxacin and other broad-spectrum antibiotics. As for those caused by phimosis, circumcision, etc., the situation usually needs to be improved by surgically removing the excess foreskin. Of course, it can also be treated with local anesthetic drugs, such as lidocaine, under the guidance of the doctor, which can reduce the sensitivity of the glans. For patients whose symptoms do not improve for a long time should consult a doctor for examination and targeted treatment according to the condition.
