Welcome. Sorry to hear about your terribly sore throat. If you have step it requires antibiotics (ATB) to resolve.
Gargling with warm salt water can sometimes ease the pain of a sore throat, along with some OTC NSAIDs but when it comes down to it you need to consult your physician.
Sorry I cannot be of more help. Strep is nasty and left untreated can be dangerous. Please don't let this go untreated. We'll look forward to your updates.
