My husband 57, is having a mild headache, tingling in face and lips, pain in tooth on left side of face. He also has a problem with balance, dizziness, and extreme fatigue for the last few days. He has hed triple bypass at 45. He has 5 stents and never has the usual symptoms when his arteries are closing. Could these be symptoms of an artery closing or does it sound like something else to you?
