Lump caused by an trichome is an uncomfortable condition which demands proper treatment. Such kind of bump forms when an ingrown hair grows back within your epidermis, triggering swelling and potential infection. Treating a cyst resulting from an ingrown hair effectively may help relieve discomfort and avoid further problems. If you're having difficulties with a cyst, seeking professional recommendations is advisable to address it properly and avoid any potential hazards associated with treating it on your own.
