What Causes Chest Pain? Chest pain is a common symptom of many heart problems, including: Coronary artery disease, which happens when cholesterol builds up on the walls of your arteries. This can make your arteries narrow, or even block them completely, raising your risk of a heart attack or stroke.
Piriformis. The piriformis is a flat, pyramid-shaped muscle that lies parallel to (in line with) the gluteus medius muscle's back margin and underneath the gluteus maximus muscle in the hip area.t takes up the most area in the greater sciatic foramen. It is a small muscle when compared to other muscles of the region. The piriformis helps rotate the hip and works with rotators such as the obturator externus and the gemellus inferior.
Both muscles assist in the external rotation and abduction of the thigh. The primary symptom of piriformis syndrome is buttock pain, with or without posterior thigh pain, that is aggravated by sitting or activity. Associated low back pain is common and can be a result of piriformis pain, but it can also suggest the involvement of other structures, such as facet joints or iliopsoas muscles.
