So I had my tonsils removed 13 days ago, the pain in my throat has gotten to be quite mild for the most part. I even quit the Percocet yesterday. 

I have however had another problem. Ever since the surgery I've had a knot in the back, right side of my neck, like a tense muscle that won't let go. It also appears that my head has a slight tilt in that direction at rest. It's become much more of an issue now that I'm off the Percocet and notice it more. Is it normal to have persistent neck pain and stiffness for this long after the surgery? Should I talk to my doctor about it? Is this something I should see the ENT about or just my regular MD?
