Hello, I've had pharyngitis since last sunday, my doctor put me on amoxicillin 500mg twice daily and i feel a tad better, but i have this annoying tickle in my throat thats lasted for up to 2-3 days and it disrupts my sleep, i woke up 3 times last night, any idea how long it will last or should i go back to my doctor? If you can get back to me that would be great thank you!
