I have had a really bad cold for the past 4 days now and it's not getting any better, it's probabaly getting worse. I have all the usual symptoms,sore throat, bad cough, headaches, blocked nose but the one thing in particular which is making it that much worse is SORE JAWS! i seem to get this everytime i get a cold so would love to know why this is and if there is anything i could do for it.
