Fork malfunction

Went to the doctor today—just a quick exam and they immediately called it inflammation. I’ve been dealing with this stiffness on my left side for the last few days, maybe a bit on the right too, and opening my mouth is pretty painful lately...
They prescribed some Amazon meds, but I really need to speed up the recovery since I’m flying out to the USA this Thursday... Anyone have any suggestions? Maybe some old-school home remedy or something similar...

thanks
