Good morning Catmom! Oh dear! You really are not feeling well. I just looked up the side effects of Eliquis and sure enough, they are exactly what you are experiencing. I can't help but think that an overeager, litigation fearful resident (inexperienced and working in the ER) saw you so worried about your occasional thumps and blips and decided to be overly cautious and put you on a blood thinner. You said it yourself, "I have felt rotten for a week now since going on Eliquis.". There's your answer.
Catmom, when I had Afib, I did not have 3 normal beats in a row and I was put on blood thinners temporarily until the beta blockers made my heart steady. Then I didn't need them. Unless you are experiencing an irregular heartbeat all the time (every 10 - 20 seconds that cause lightheadedness, I doubt that the cardiologist will consider you to have Afib.
Keep in mind that often the cure is worse than the disease and those blood thinners have strong side effects...as you have noticed. How about aspirin if absolutely necessary?
Btw, you don't always have to go the drug route for everything. For reflux (which I experience), baking soda in water works. For stress, there's exercise. For borderline diabetes, there are dietary changes. My aim is to AVOID drugs as much as possible. To me they cause side effects that then need more drugs to control them.
Your blood pressure is perfect, your oxygen levels are perfect, your pulse is perfect, your weight is perfect and your blood sugar levels are almost perfect (up the veggies and protein, lower the carbs). Rejoice!
Are your thyroid levels normal btw? That could be the cause of any weight loss AND your nerves.
I predict that the cardiologist will send you home with a clean bill of cardiac health and tell you to keep away from the stimulants and excess sugar/carbs and to go to the gym. And to relax!
