Dry gagging cough, weight gain, charley horse in calves, but worse of all when I use the bathroom I have a terrible burning sensation in personal area of my body. Am using baby wipes instead of TP. The burning subsides for a while but of course is back when I have to use bathroom again. I think the diuretic in this pill may have some bearing on this symptom. I was checked for a bladder infection and it was negative, although a minute amount of red blood cells were found in my urine. I too, have had the very low BP readings, 90/68, etc. The first time this happened it frightened me so bad I got up and ran around our house and took BP again and it had risen within the normal range. I was on Hyzaar and my present doctor could not understand why I was on such a strong BP med. So he changed my to Lisinoprol HCTZ. Anyone having the same effect?
