A wart, as it is commonly called, is a common dermatological wart, a skin disease caused by a viral infection. The old folk saying is that the wart can be strangled to death by tying a string around the wart’s root. This photo above is a typical example. After strangling the wart with a rope, instead of killing the wart, the bad stimulation caused an infection at the base of the wart, resulting in redness and pain. So, what is the regular treatment plan? You can go to the dermatology department and use local anesthesia followed by laser removal, which is safe and effective.
