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.
Piriformis syndrome occurs when the Sciatic nerve is compressed or pinched by the Piriformis muscle. Indications include sciatica (radiating pain in the buttock, posterior thigh and lower leg) and the physical exam finding of tenderness in the area of the sciatic notch.owever, compression may be present, but not causal, in the setting of sciatica due to piriformis syndrome. The syndrome may be due to anatomical variations in the muscle-nerve relationship, or from overuse or strain.
