Takign Paradaxa. Lacked Energy. Having Knee And Hip Pain. Feel Dizzy And Losing Balance. What Can Be Done?

I take 150MG of Pradaxa 2x a day along with 25MG of Metropolol for Atrial Fib. I have taken Pradaxa for 1 year and 1 month, and almost from day one, I lacked the energy I was used to having. Over the year my knee and hip pain has increased, and I have visited emergency room 3 x because I am 'Off Balance". I am not dizzy per se, but fall to the left or right with eyes closed and sometimes am unable to prevent it by holding on. It happens. I have had catscan and MRI that show no bleeding in head, and have been referred to Dizzy Clinic for appraisal. Cardiologist and doctor say to stay on drug as it will prevent stroke, but I need alternative. I have never felt so poorly. I still experience AF, my blood pressure is in check most of the time, sometimes lower than 120/80. I eat very well (healthy).
