One time this morning and one time this evening. Light headedness, at same time ripping burning shooting pain across upper back between shoulder blades,as well as left arm pain and cold/numb down arm into hand. Also same time have horrible right side lower jaw pain,burning, tightness, like can not speak or swallow. These episodes lasted 5-10 minutes each time. I have to lie down with legs bent to help ease pain. My e-mail is YYYY@YYYY .
