I am 53 female w/SLE, systemic lupus for almost 10 years. Barrett's esophagus, GERD, gastic paralysis, fibromyalgi, chronic fatigue, Sicca syndrome, list goes on.....This is something new...sudden very severe shooting pain going up right side of neck, carotid area, sometimes into ear, but not always. Relieved with nitroglycerin. Any guesses as to what this could be?
