blood pressure

My last bike ride was Christmas Eve. I haven't ridden since then due
to health concerns. I reported last week that although my wife was
very ill with the flue, I had escaped it, which may have not been the
case. Although my temperature remained near normal, I did have other
issues, the most serious was a dramatic increase in my blood pressure.
My normal systolic pressure is under 120 and for several days last
week it was above 130, one morning it was 139.

First thing this morning is was back down to 121/77, and now after
breakfast it's 114/59.
