 [ Symptoms ] i had viral phrayngitis about 2 weeks ago and i think its back what should i do is this going to keep happening [ Disease ] i do not know my unlucky friend there are over two hundred different viruses that have the potential of causing viral pharyngitis you had one two weeks ago and now you may have another one 198 more to go i suspect that you did not get it back but rather got a new viral infection that also loves to take up residence in your throat you can thank your friends and relatives for the exposure and blame your immune system for not fighting it off
