Diurectic symptoms and conditions

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?

I began a new dose of Prednisone yesterday. I was diagnosed w/ RA about 3 years ago. I have been on Embrel (didn't work) and am now on Humira and Methotrexate. I have been having extreme difficulty the last month and finally returned to my doctor for relief. (I have been on Prednisone before and had only the headaches) I was prescribed a higher dose this time (60 mgs 2 x daily) and have been battling with a racing heart that beats so hard it hurts. I have now taken my second dose and cannot walk more than 10 feet without feeling like I am having a heart attack! While it is helping the RA pain in my joints, I am so scared to move and so uncomfortable when I do, I am not sure what is better. The disease or the cure? Has anyone else battled with the racing heart? Oh and I also have high blood pressure and the Prednisone is making it higher even with my meds!
My only other instance with this effect was from a steroid injection about a month ago. That episode placed me in the ER receiving medication to lower my heart rate.
