Why when running pain in my side?

If during fast walking or running you felt a stabbing pain, you should know that in the right side it hurts the liver, and the left — the spleen. The explanation of the causes of such pain are quite simple. When the body is not exposed to stress, the part of blood is placed in reserve and does not circulate through the blood vessels. The main volume of circulating blood falls on the chest and abdominal cavity. Physical exercise causes a redistribution of blood flow through the body in favor of muscles that work.





It should also be noted that unlike muscles, ready to immediately start work, autonomic functions, which provide their work (such as circulation and respiration), you need some time for "bedding". In cases of heavy load without a preliminary warming-up "backing" the blood begins to flow into the bloodstream, while not having to quickly flow away from the liver and spleen.





As a result, blood fills the abdominal organs, increasing their sizes and creates pressure on shell. The shells are pain receptors, they signal a stabbing pain.
