high blood pressure
"80 mg valsartan is the 1st BP med I have ever taken.  After taking my second pill I developed an extremely severe headache in the front of my face.  It subsided the next day but did not go away completely.  After the 5th pill I experienced pain in my hips, knees, and fingers that woke me up constantly during the night.  I took another pill the next morning.  That evening I developed a severe rash on my face right across the areas where I had my headache.  Did not take another pill after that, but still have a headache after not being on it for a week.  My BP was 148/83 and never really saw much of a difference being on the pill for such a short period of time.  Valsartan made me feel very unwell!"
