Hello!
I read carefully your query and understand your concern.
Your symptoms might be related to a viral infection,cold or just inflammation of your throat due to irritation from smoke.
If you have no fever,your throat is just red without
white spots or other findings, you don't need to worry.
Usually it is a self-limiting condition and no specific treatment is needed.
You can use cold drinks to relieve the inflammation,water salt gargles can relieve the symptoms.
For the headache you can use
Ibuprofen or
Paracetamol.
You need rest,eat healthy foods mostly green vegetables and drink plenty of fluids.You will feel better day after day.
If you have
high fever, white spots start to appear on your throat,have difficulty swallowing,
difficulty breathing or if these symptoms last more than 1 week then you should seek medical attention, otherwise you don't need to worry.
Hope my answer has helped.
Take care.
