high blood pressure
"I take Valsartan 80mg once a day for BP but BP is never stable. It lowers the BP but sometimes it's as if I haven't had any BP medication. 
Along with this, there are an awful lot of strange sensations throughout the day. I've been taking it for 3 months now. 
Side effects: from feelings of tightness, palpitations to lightheadness and right side of abdomen flushing pains."
