Without any warning and for no apparent reason whether I am sitting,walking, or what ever, I get a sudden temperature rise which causes me to sweat profusely for a 2, 3, 4 minutes, by which time I am wet in my upper body and head. Once this sequence is over, that s it. It is totally random, whether I sat still or working. It can be days or weeks between these events but over the last 2 days it has happened 3 times each day, and once again, so far, today. Any contributions and opinions will be much appreciated. Thanks, Andy Pandy,
