I'm currently sick I have flu symptoms it begin Saturday at work. I normally don't work on Saturdays, I do HVAC work for a living. We were doing a big residential project that needed to be completed in a certain amount of time. It was an attic installation prior to Saturday I spend three other days working in the attic of the the big project. The 2nd day temperature in the attic were up to 110 degrees, I do my best to stay hydrated. 3rd day I was physically exhausted by the end of the day which was Friday. I had a poor choice for dinner that evening, burger King double whopper I ended up going to sleep late at 1pm. Saturday morning I woke up feeling physically sore and sleepy but no symptoms of flu like. At around 12 noon my body felt awkward my nose started bothering me felt serious discomfort through out my body, eyes were sensitive to the light, continue to get worse. I have two questions, first any idea of how I could of been exposed to the flu? Lack of sleep? Poor nutrition? Question two how can I overcome the struggles of my eyes being sensitive to the light when I'm sick? Is it something your born with genetically?
