Thank you. Husband 72 yrs. old having A-fib for close to 20 yrs. Taking many rx drugs pertaining. Has pacemaker. Also taking morphine and hydrocodone for spinal stenosis, spur, etc. Taking Coumadin also. When taken off blood thinner for short period for minor surgery had stroke each time. Now, the problem is extreme weakness and at times bleeding from stomach and pain related. At this time, no bleeding or stomach pain just extreme weakness. Had blood work this past Dec., not anemic. I am hoping to see his gp soon, then on to Cardiologist. I really feel it is the combinations of all the meds. I can give you list if you need it. Charlotte Young
