Root canal < 1 year ago, feeling pain and freaking out

[jumping_dog99]

Got a root canal + crown 9 months ago - X-ray attached (bottom tooth, lower right). I have TMJ and am experiencing some jaw pain, but not specifically on that tooth. The tooth doesn't hurt when I eat and does not hurt when I tap on the specific tooth, but jaw is slightly sore and tingly, feels better with heat. This is the only X-ray I have unfortunately

I maxed out my insurance so really need to know if I should go in ASAP or if I can wait until jan

26 year old female, do not smoke, no conditions just some bad teeth lol

Is this tooth infected? Is the crown too big? I am freaking out
