Thank you. I recently had eye surgery. Prior to the surgery I had a complete physical including blood work and EKG. Two weeks before surgery and 5 weeks after, I had to take various drops. The drop Prednisalone Acetate would drive me crazy. It would make my heart palpitate and my head throb. I stayed with it because the Dr insisted. I take no pharmaceuticals, not even supplements. I train every day. I am totally organic. My training consists of cardio and weights. I am 65 and have been training consistently for over 35 years. I do not smoke and have not had read meat for over 30 years. I stopped the steriod 2 weeks ago, but I still during the day have the same weird feelings. I have been training and have no loss of strength or endurance. I do not have shortness of breath. However, this palpitation and head throbbing makes me nervous. My question, could it take this long for my body to throw off the effects of the steroid? Thank you!!
