Twitching above my ear

[agoraphobic]

Hey guys,

Recently, I've started to get a twitch on the side of my head, right side, about 1/4" above the top of my ear.   It started three days before X-Mas... then went away.  It came back last week Thursday, and I've had it most nights since.

I don't have it during the day, only at night when I lay down to go to bed.  Normally I don't have a headache with it, but I've been worrying about it a lot, and rubbing my temples looking for it during the day.  This twitch ONLY happens when I lay down to go to bed (or shortly after), and it really only can be felt when I lay on the right side of my head when I go to sleep.  It feels like a finger is tapping me when I lay down.

Now, i don't know if twitch is the correct word.  It's not a pulse, because the movement is completely erratic.  It doesn't match up with my normal pulse. 

History on myself.  29 years old, and in good shape.  Normal blood pressure, and great cholesterol.  I'm prone to panic attacks, I tend to worry about my health to much, and am under a lot of stress with my new job and having a family (married, and have a 5 year old).  I tend to believe I have something wrong with me physically, most of the time.  Usually goes from thinking i have a heart problem (have had a complete heart work up at the dr), to my brain (aneurysm or tumor), to skin cancer (mother in-law died from that), to a blood clot (do to me sitting at my job) to now where I think I might have Temporal Artrisis or a artery under my scalp ready to BURST. 

The first time I had this twitching, I just got over the worst case of my TMJ acting up.  The week before X-Mas, after that Sandy Hook shooting I got into a nasty argument about gin control with a few people, and I noticed I had grit my teeth so hard, I couldn't move my jaw anymore.  Took me a little bit to get it to open 1/2", and the next 5 days to get it back to normal.  Now, could this just be my muscle above my ear, twitching?   If i open or shut my jaw hard, the twitching stops until I relax my jaw.  My second bought of this started after I banged my head hard under my table..... my head was fine, but I was worrying constantly that I was bleeding in my head (grandpa died of a hemorrhage in the brain).

I've also been hitting the weights harder over the past month... lifting heavy = jaw clenching.
