There isn't sufficient information to give a specific diagnosis. Details such as character of headache, aggravating and relieving factors, etc are required to make a proper diagnosis. I would advise you to visit the ENT so that you can be examined and undergo investigations such as CBC,
thyroid profile, BP monitoring, etc. to find the underlying cause and have it treated accordingly. For the throat pain I would advise you to do salt water gargling with lukewarm water thrice a day.
