What causes medical problem of sudden shaking, cold feeling and upset stomach? Only lasts about 2 - 3 hours. Heart rate is fine and symptoms appear like beginning of flu, but go away in a couple of hours.
Any history of thyroid dysfunction?
Are you taking any medicines?
Since when are you having these symptoms?
Does the shaking feel like tremors?
Lots of medicine for heart, etc. Have had 5 hip replacements. Weight is slightly under weight, 90 pounds, but Dr. is not panicking about it. Symptons started Tuesday when I was at a urology Dr. appointment. He checked heart, blood etc and thought I was getting flu. I went home and went to bed. Better by night and well the next day. Happened again today, but did not last as long. Not like tremors, more like being cold.
The shaking you feel could be due to Hypothermia (Lower Body temperature), since you mentioned associated cold feeling. Since your blood work and clinical examination is normal I won't worry much.
