Scoliosis is very commonly diagnosed and can differ from person to person in severity. Some people have a very obvious curve and others walk around with low back pain and/or hip pain without understanding why. True scoliosis happens when the length of the legs bones differ from one side to the other. A tight psoas muscle (pronounced soaz) can give the appearance of scoliosis. The psoas muscle attaches the hip to the low back. When the psoas becomes tight, it can misalign the hips, cause low back pain and/ or cause the buttock muscles to feel tight. It can also give the appearance of a hunchback and hips rotated forward which can also cause neck and shoulder pain. Massage therapists who offer postural correction can tell be looking at the posture if the psoas muscle is tight. My husband was born with scoliosis. A tight psoas muscle was the only thing wrong with him. When he was a baby, a doctor pulled his legs down to meet each other and told his parents that he would grow out of it. When he was older, he was told by a doctor that surgery to put in a metal rod was his only option.
Some good self care for taking care of a tight psoas muscles after after it worked on by a therapist is walking and yoga. Laying in an inverted position to 30 minutes a day helps too. There are some contraindications to laying in an inverted position such as menstruation and high blood pressure. A lot of sitting and driving is a common cause for a tight psoas muscle.
