I am sure you have heard the term, but what does this means?
When you have a referred pain, means that the source of the pain is not the area that is hurting, it means that the pain is being referred to a different part of the body, it could come from an organ or another soft tissue in the body, also pinch nerves.
This can happen in many parts of the body that share the same nerve pathways, for example the pain that is felted when someone is having a heart attack it may be feeling pain in the left arm, even the cheek.
Some other pain sources that you may experience is your liver or gallbladder can give you a pain in your shoulder; a heart affection could be felt as pain in neck, shoulder or upper back. An injured of your wrist can be felted in your shoulder, a kidney problem can be felt as a pain in your back below the ribs.
A problem in your abdomen can be felted as pain in your upper back or right shoulder. Also a lung affection can give you referred pain in your back.
A pain that goes from the lower back all the way down to your foot or from the lower back to the back of your knee is most of the time the famous sciatica pain, which means that your sciatic nerve is being pinched or got hurt somehow, maybe an spinal injured that is putting to much pressure on the nerve, this kind of pain also can be felted in the frontal part of the leg and this means an even more serious damage.
