I’ve had the same problem recently. Bernie is sending me something to help. Said it’s an infection of the addenoids. Once my pack comes from him, I’ll let you know exactly what’s in it. I know he wants me to do a nose wash with kosher salt.
My issue started totally randomly and when I saw a nurse at minute clinic they said all looked normal. Good ole modern medicine!
I don’t see how chamomile would cause a reaction though. Seems safe and is antifungal. Could it be something else you ate?
