Pain can simply be defined as an annoying or unpleasant sensation that limits a person's ability to carry out their normal daily activities in an independent manner. It can also be taken as an early warning sign that your body is not in a comfortable state and calls for appropriate action. The perception and intensity of pain varies from person to person. A person with a broken bone may not even feel it, while another person may experience significant pain from a minor injury, bruise, or cut.

Pain is one of the most complex processes and is controlled by the body's central nervous system. We usually feel pain when we touch a hot surface or get an accidental cut or bruise. Pain receptors that help us feel pain can sense pressure, light, cold, heat and pain.

It is a fact that when you do something that causes pain or discomfort to your body, the brain usually triggers a response that something is seriously wrong with your body. You can also use over-the-counter pain relievers, such as OTC Tramadol 50mg, which you can easily buy at an Pharma Health online pharmacy, to relieve pain.
