For your throat issue, try gargling several times a day with about 1/2 cup warm water that has some salt (make it about as salty as ocean water), a teaspoon or two of apple cider vinegar, and if you can stand this part - a dash of cayenne pepper. If you can’t take the heat of this ingredient, omit it. Gaggle as deeply as you can allowing it to get very far back into your throat. Do not drink anything for at least a half hour afterward so that it stays on your throat. I got this tip from a professional singer who needed her throat and voice in top notch condition. Hope you get relief.
