My symptoms are simply that I keep sweating if I am in a hot
environment and usually when eating a meal. Last night for
example, I was at a Christmas dinner party and sitting at a table
with eleven other people of various ages and fitness levels. One
chap there has high cholesterol and high blood pressure for which
he takes a prescribed drug.  

The problem is, I was sweating profusely, esp my forehead and
underarms, while everyone else looked quite comfortable. I also
occasionally sweat at night, but only around my neck, chest and
top of the shoulders. This is the only symptom I can think of,
but it is becoming very uncomfortable,

I had a serious RTA a couple of years ago, which resulted in nine
broken ribs, a broken sternum, a lung infection which led to a
collapsed lung. I later contracted septicaemia in the hospital
and I was kept unconscious for one entire month. This has got me
wondering if perhaps my blood circulation is poor?
