I am on 6 mg prednisone, 80 mg of Valsart. I am 85 year old female. and seemingly in good health. I have had an ekg, came out good. blood work good, however, I have blood pressure variations from 98/65 to 167/84. waves of faintness, shakiness, and sometimes a fullness in chest. No Dr. seems to know what is wrong with me. Symptoms seems to relate to Valsart.
