I have been taking Diovan for 3 months, and I developed bad coughing for more than 5 weeks. I stopped Diovan 5 days ago and I feel much better (no cough), but my head is about to blow and my ears are burning. The doctor is saying that diovan is the best for my age (33 yrs) as everything else could have much worse side effects, impotence in particular. Any suggestions? (I was taking Diovan 80 once a day).
