high blood pressure
"I took 20 MG Benicar as an alternative to Lisinopril which caused a cough.  With Benicar, the cough went away after a few weeks but a new side effect took its place: I would wake up in the middle of the night with a sore chest and upper back pain.  Its a shame because during the day, Benicar had no apparent side effect and kept BP at 128/79."
