I Have A Sore Throat, Fluid Behind My Ear,a Lot

I have a sore throat, fluid behind my ear,a lot of mucus and congestion. The strange thing is that I have bumps on the top of my hand and random itchy bumps here and there on my body. There seems to be a virus going through hour home. My 3 year old just had what I think was hand foot and mouth with similar symptoms as well as what I think was viral pink eye. Could my symptoms be hand foot and mouth?
