Hello, I am currently experiencing some low blood pressure, headache, impaired vision, lower back discomfort. By blood pressures for the last hour or so has been 76/57 hr 114 67/44 hr 106 75/55 hr 10779/59 hr 96. It started dropping this morning 91/64 hr 115. Normally I have high blood pressure and I am currently taking Ramipril 10mg 2 times a day, Triamterene HCTZ 37.5-25mg 1 time a day. I am tired and worried about passing out when I stand up. Currently I am at work. I also has a touch of insomnia which I thought might be the problem. I don t drink, 5 2 , weigh 206lb and a casual smoker. Just wanted to know if you could tell me why I might be having these problems. Thank you Kim
