Jaw pressure and episode with not shutting?

I was very anxious for about 3 weeks and had a viral and thrush infection ontop of it. At that time I started getting jaw pressure and for two days I had spells where my jaw wouldn't shut all the way. When I would relax it would slam close, like a muscle spasm. That hasn't happened for over a month now but I still have uncomfortable pressure in my left jaw. My bite is off and I have always been able to crack my jaw on that side though it doesn't crack when I open on its own. I can open my mouth wide and eat fairly good. I feel more pressure when o lift my head all the way up. Does this sound like tmj or something else?
