I have been having this troubling symptom for a number of months now and have found it difficult to explain to those closest to me. A sort of rushing in the ears in time to your heart beat. I haven't mentioned it to my GP just assuming that it was either a Pred side effect or raised blood pressure meds. Causing it. After a bit of Internet research I realise that it does need mentioning and could be associated with forms of Vasculitis.
I prefer to go to the GP armed with some knowledge and options. I don't want to be brushed off or sent down another unconnected medical path. This symptom has only appeared within my PMR time frame and I am sure it is associated. Thanks!
