Not sure if this is anxiety or reaction to blood pressure meds, so I wanted to see if anyone has similar symptoms. When ever I walk, such as on my lunch break, I have been getting weak knees, heavy legs, and pressure in the top of my head and ears with feelings of lightheadedness and anxiety the longer I walk . I'm currently on Benicar HCT 40 mg for about a month now for HBP - prior was Benicar HCT 20 mg, benicar 20 mg, and bystolic 10 mg. I've also been under a lot of stress the last several months, and have had episodes of anxiety/panic attacks. The heavy leg feeling has been getting worse lately. I've had blood work done (all normal) 2 EKG's (both normal) and a ct scan that was also normal. I'm at wits end. I go back to the doctor to evaluate how the blood pressure meds are working. Anyone else have similar problems?View Thread
