I have a sore dry throat and a cough aswell as a headache ears popping and a stuffy head what could be wrong and what can I do to help it?

Viral. These symptoms are consistent with a viral upper respiratory tract infection(head cold) that should run its course in several days to a week. At this stage, decongestant pills(if you're not pregnant) and nasal spray as well as tylenol (acetaminophen) are helpful in relieving symptoms. See your physician if there is worsening cough, wheezing, new fever, chills and sweats.
