Hi,Chris,thanks for query.Normally after any major surgery the intestine have tendency to adhere to each other known as adhesion
.this is a normal response and happens to many.At times when the intestine tangles in between this adhesion the body makes intestine moves very frequent which gives rise to pain and discomfort at times.Again this has nothing do with your lower backache
and tail bone pain
.At your age it is mostly muscular and may related to your faulty working style which puts stress
on the back muscles.please do not worry.you can discuss with your doctor for more information.bye.
