Non TMJ/Bruxism case of sore jaw
I had orthognathic surgery (upper and lower jaws) in 2011. About a year ago, I started waking up with severe pain in one side of my jaw and having difficulty opening my mouth. This lasts for a few weeks then it goes away, then a few months later it comes back again. If I take ibuprofen before going to bed, there's no pain in morning, which makes me think that this can involve an infection. I do not clench my teeth (my upper and lower molars don't even touch) so I don't think it can be a case of bruxism.
Unfortunately, I am living abroad right now as a student and my health insurance doesn't include dental coverage. I don't want to go to an orthodontist here because I don't even speak the local language and can't afford a consultation.
I need to have an idea of the possibilities of what this can be, if it's not TMJ.
