MID AND LOW BACK MUSCLE DISCOMFORT
Trigger points can be found in the taut band of muscles in the posterior mid
and low back regions. The large muscle groups of the middle and low back
are generally responsible for maintaining good posture in sitting, standing
and lying down. Many people lift, carry, push and pull during work and
leisure activities. However, some weight may be too heavy, an awkward
size, or lifted too often with improper posture. Over time, repeated stress
to the back may produce sore, tight and stiff muscles. Muscular back pain
can also be a direct result of illness, trauma or injury.
