Not sure if my recent problems are related, but four weeks ago got sore throat, lost voice for 4 days, then persistent cough since. Then my daughter caught stomach flu, which passed to my son, then my wife and me. They all had symptoms of throwing up, but mine was diarrhea and has lasted longer; now at day 3. Just noticed I have a big bruise on my right arm, don t remember bumping it and have never bruised before in my life. Also have soreness behind hinge of my jaw on right side.
