So this has been on my mind for a while now. About a year and a half ago, I went to see my Vascular Specialist. It was a Friday. My waiting time upon arrival at the office was one and one half to two hours. I questioned that to the sign-in nurse. They said "Do not come on a Friday ever again." Alarmed, I asked why. Their response was that they had elders who had waited far too long to seek a Vascular Doctor's medical attention and nothing could be done for them, sadly.
My point is---kindly see that your elder (or even yourself, for that matter) gets to the doctor sooner rather than later. Later is an inevitable failure.
