I've been getting consistent high readings ranging from 130/80 to 140/90 and more often the upper range. My wife has been measuring it for me for the past few days. I've also used the stationary machines in pharmacies. I do about three readings in a row, and the first one is always higher; then the second time it's lower. For instance; yesterday I've used a stationary machine. The first reading was 133/78. I waited a few minutes and measured again; the reading was 121/76.

I'm just wondering if my medications are causing these high readings. Any input?
