Suggest Remedy For Muscle Spasms In Cheeks

About 2 months ago I seemed to have a muscle strain in my trapezious muscle. It was pretty bad and it effected both sides of my back and neck ... The left was worse than the right. Slowly it has gotten better. However about 2 weeks ago or so i noticed that my right cheek was having minor spasms. It seemed to occur as the right was just about getting normal. It went away after a day. Now my left trap seems to be almost 100% and the spasms started in that side. It is noticeable when i make a big smile. My cheek muscle feels like it is stuck for a 1-2 seconds. Is this part of healing or refered pain?
