I also developed very sore gums and what appared to be a herpres sore (white, round, tingly) on the inside of my lip
. I also developed what appeared to be herpres on my penis. Four-five small red bumps with small whitish/grey centers, one of which turned into more of a crater-type chancroid, grey/white in the middle, sore to touch. I also developed a cough. Within 2-3 days, the flu symptoms were gone, and within a week to two my mouth and penis had heeled.
