I have occassional blurred vision, occassionally feeling like i have sick in my throat. Blood pressure can rise after not doing too much with heart flutters or feels like its racing at times. Been feeling like this for about 4 weeks. When it first started my blood pressure was high and heart rate higher than should be, also had numbness in left hand on and off for a couple of days. Then had tingling for a few days. I seen the doctor who put me on tablets to slow down heart rate which made me get cramps up both legs and did blood tests and says all is fine. I still dont feel right in myself.
