Hi, In The Last Few Days I Have Had A

Hi, in the last few days I have had a slight sore throat on one side and then thought it was a sore tooth, that went away and replaced by headache with pressure feeling and pain on side of my face. Also getting twitching of my scalp on one side. Also popping sounds in my head but I have had that before. What do you think? I have to fly tomorrow and am concerned about that. Thanks Louise
