Suddenly in alot of pain!

The past two days I have been having sharp pains behind my left ear ad down my neck to the top of my shoulder. This last one has left me with a headache in my temple areas. HEres some backgrouNd info. I have started smoking again.. Not more than 3-4 a day, with no breathing or chest problems or anything with it. Im currently about 5-10 pounds overweight. And my wisdom teeth are starting to break through my gums. I also supposedly have tmj. I just want to know if it's something serious sounding or if it's most likely dental problems. Any feed back is greatly appreciated!! :) oh also the pain isn't constant I just have a hand full of 30 second- 5 minute spells each day. But it's definitely not a fun feeling.

Much love and god bless.
