There are 3 types of pain, with the first being acute. Acute pain is a sharp or stabbing type of pain that typically lasts for less than one day. The second type is chronic and this can last months or years. Chronic pains are far more difficult to manage because they do not respond well to treatment over time; however they still feel completely normal during those times when its at its worst. Finally, cancerous tumors provide an extremely painful sensation where you would feel as though your whole body was on fire even though there isnt any actual heat coming from the tumor itself.
