mine was like that for several days also, it felt more like dry throat rather than sore though.

its more like that it only hurts when I eat something and its just a ping pf pain but I have had it since Monday

Mine felt dry like not enough liquids like water and juice.

Your eater have Strep Its a bacterial infection (need anti biotics) or its from allergy and drainage and you need a antihistamine Look it up on web MD or ask a doctor or Pharmacist

does it feel like your swallowing glass when you swallow food?

i have the same problem. still sore but is coughing a lot of mucus all day and night yesterday.still bad. my inhaler has help open my tubes so i can cough out the blockage i had in the middle of the night. mine might be bronchitis so i might have to get some antibiotics but doctors are shut on weekends
at least the inhaler has helped so might be able to fight it off without the antibiotics. if only i can fight this flu off

Trust me you have to do something about it right away
