Help with strange feeling after EPS?

2 weeks ago I had an EPS study done of my hearts electrical circuitry. I am 50 years old and a survivor of a heart attack 10 years ago. The study was 5 hours long and the a-fib arrythmia was not able to be reproduced during the study. After the procedure I was fine for a 3 days - then sick and in bed for 3 days. The symptoms were flu like with nausea and vomiting. Since those days have ped I have been feeling generally unwell. Fatigue is the top of the list with my extremities seeming like they weigh 500 pounds. I have a chemical taste with every breath and a ringing sensation in my ears. Every once in a while my blood pressure seems to drop and leaves me feeling like I am going to p out. If you have ever had the flu and fever and have had that disconnect or disjointed feeling that is how I seem to be feeling every day. It comes in waves and is really bothersome. Has anyone else experience this after this type of procedure? Is there any comments or suggestions on something that I can do. I have seen a doctor in Emergency and all tests show blood levels fine, no cardiac markers. Something is just not right and I dont know how the heck to get anyone to listen or check me out.
