Thanks for writing to HCM. You seem to be having a pharyngitis
which is an infection of your throat. Pain and difficulty while swallowing does indicate an acute infection.
I would recommend you to do warm saline gargles and take an analgesic
. Avoid smoking/ alcohol/ cold and acidic foods. If not better, see an ENT Specialist
, as you may need prescription antibiotics or may require further testing of the throat with a throat swab. Hope this helps. Do let me know if you have any other doubts.
