I am on day 5 of a cold or virus. Began with a very sore throat and swollen glands, but no congestion. Looked like strep with red bumps, but strep culture was negative. Then it turned into a horrendous head cold. Today, I am back to just a bad raw-sore throat, but now my throat looks like blood vessels have broken in the back of it. Should I go back to the Dr. or is this just from blowing my nose 1000 times?
