Pain is a general term that describes uncomfortable sensations in the body. It stems from activation of the nervous system. Pain can range from annoying to debilitating, and it can feel like a sharp stabbing or a dull ache. Pain can also be described as throbbing, stinging, sore, and pinching. Pain can be consistent, can start and stop frequently, or can appear only under some conditions. People respond to pain differently. Some people have a high tolerance for pain, while others have a low tolerance. For this reason, pain is highly subjective.
