It should be WARM salt water.

There's not much you can do otherwise. Just wait it out or get some antibiotics to speed up recovery.

Take Vitamin D and I like to use an anti bacterial anti fungal lozenge called Decaquine. Not sure if it is available in your area or not but it is much more effective that strepsils which in my experience might as well be drinking water.

What always works for me is a nice cold Coke and a bag of salt and vinegar chips. I don’t know what it is, but that has always worked for me.

Also put Vicks vapour rub on your neck and then rub a scarf around it

Salt water helps me, also honey

Yes gargle with hot salt water. And drink Lots of hot liquids like hot green tea with honey and lemon, lots of soup with garlic, curry, and veggies,

Fireball

The salt water thing or honey and lemon tea

That was a standard response growing up and still use it

Take some ibuprofen

Gargle diluted TCP

The fact that you said "sucking" is SOOOO HOT! 🥵
