Stop sitting on the problem!
The pelvis is the basis of all of vertebral column, if the pelvis has the slightest inclination, this translates into a mismatch in the entire body.
Sitting in the portfolio creates an imbalance that the column will try to compensable by putting more pressure on (specially sacroiliac joint) joints, muscles, ligaments and the nervous system. In the long run can cause serious problems in the spine or sciatica. We recommend you to visit a chiropractor.
