Both myself and my mother(she is in her 80 s) and I am 55 are experiencing weird symptoms: I had it since Sunday evening and seemed better by Tuesday, but now it is kicking in me again, and she had problems yesterday and today now. Our symptoms are: fatigue, hot to cold sensations, feeling sick in our stomachs, and wierd greenish, algae looking bowels. Could it be a stomach flu in the summer? Or something we ate?
