Hello and welcome to HCM,
I have understood your concern regarding the consumption of hot food leading to pain
Like you correctly assumed, when you took the hot food you might have caused some
injury like burn or otherwise to the throat.
This is why you may be feeling the pain
You can start a pain killer like
paracetamol and antibiotic like amox -clav 625mg for five days. Your doctor will know about the this
You can also start tablet
pantoprazole in consideration with your doctor
Take only bland non oily, non spicy food
Do not strain while you speak
Wait for about a week and if you do not get better then get an upper GI
endoscopy and get back to me with the report
Get well soon
Regards
Dr Sriram Nathan
