You are being treated for heartburn or hiatal hernia, and you feel sudden chest or stomach pain, have difficulty swallowing, are vomiting, or are unable to have a bowel movement or pass gas; you may have a hernia that has become obstructed or strangulated, which are emergencies.
One strong possibility for your symptom is gall bladder stones and cholesterol deposits within the gall bladder which can cause sharp pain. Getting an ultrasound of the upper abdomen done in a walk in clinic or the ER will confirm the diagnosis.
At first, the right leg is held in a horizontal position. By using the left piriformis muscle, raise and lower the right hip up and down (arrows). Once the left hip fatigues slightly (after about a minute), touch the right leg to the ground by pulling it back and towards the left (arrow A). By varying the degree of hip flexion (arrow B) you can isolate specific muscle fibers of the piriformis responsible for limiting motion. View Larger Image.
