I have just had / having a flare and as it is affecting my sinuses have been prescibed antibiotics by my Rhuemy who I rang for advice, I was taking these for 7 days , at the same time I had been prescribed 30mcg Prednisolone for 7 days, now taking 20 mcg for 7 days then onto 10 mcg for 7 days and finally 5mcg for 7days. However I am getting a very irregular heart beat, I feel as if my heart is pounding one minute then almost stopping the next ,I can also feel a pulsating sensation in the front of my neck and it feels " very odd " I don,t feel dizzy or faint and I do feel I,m improving ----- except for the very uncomfortable and rather frightening change of heart rythm. My blood pressure which is usually around 134 / 90 ( I am not on blood pressure tablets ) has been , over the last 2/3 days sometimes around 157/ 116. then later goes to 90/55 and also 137 /95. Of course it being a weekend isn,t helping, so just wondered if anyone knows if this is likely to be the steroids , and has anyone had similar problems.I haven,t had this problem before on Prednisolone, and am not taking any other medication for Vasculitis. Thankyou for any advice.
