Bump caused by an ingrown trichome may be an unpleasant issue which demands proper treatment. Such type of cyst develops when a hair grows back into the skin, resulting in inflammation and potential infection. Managing a cyst resulting from an ingrown hair properly can help ease pain and stop additional problems. If you're dealing with an ingrown hair cyst, seeking medical recommendations is advisable to address it adequately and avoid any potential dangers associated with treating it on your own.
