Massage therapy relaxes muscle tissue, which reduces painful contractions and spasms. Massage can also reduce nerve compression. To understand this, consider that when muscles are contracted, they sometimes compress the nerves around them. When these muscles are relaxed, the nerves are no longer compressed, and, in theory, can get proper nutrients and operate more efficiently. The nerves can assume their normal work of transmitting messages to and from the brain, which improves the functioning of the muscles and organs.
Organs can also benefit from massage, as they share neurological pain pathways with muscles, bones, and nerves. When muscles, bones, or nerves are distressed, organs can sometimes reflect distress and dysfunction. For example, low back pain can intensify menstrual cramps and menstrual cramps can cause low back muscles to tense. Massage can therefore improve symptoms associated with the functioning of both the organ and the muscles.
