My husband is 63 years old. Smoker, 40+ lbs overweight, heart skips a beat, on eliquis, The past week he has felt fatigue, dizziness, throat (esophegas) is sore to swallow and just sore, and just all around not feeling up to par. He has seen his heart Dr. 2 weeks ago and his primary Dr. about 6 weeks ago. He was feeling fine during these visits. Just the past week+ he has been feeling unwell. Any clues?
