It’s been years so I wonder if you have any answers????? I HAVE THE EXACT THING YOU DESCRIBE. I’ve been to the chiropractor for months without any relief. I’ve sought TMJ treatment without any relief. Please let me know how you are doing. Mine is on the left side as well. I have the exact pain you described and the puffy eyelids.
Since the pictures of your head and neck are okay, and your heart is okay, then what comes to mind for me is, you could be something as simple as a tooth infection. I know, you wouldn't think that would cause all this misery, but I can tell you from personal experience that it can.
Feel of your lymph nodes in your neck....they are located between the throat and the corner of the jaw. If they are swollen and/or sore, that's the lymphs fighting off infection. It can make your ear hurt, your face hurt, swell up your eyes, and the infection can spread into your chest and head, which is actually a dangerous situation.
So, just to be on the safe side, get thee to a dentist, have him look on the side where it hurts all the time, top and bottom, and he'll X-ray those teeth, and then he can advise you if a tooth needs pulling or whatever! He may also give you some dental antibiotics, too, and might even want to drain any pus that's gathered there. Sometimes these things are not visible to the naked eye, so that's why you have to (a) tell the dentist where it hurts, and (b) let a dentist diagnose the problem.
If you have not yet been to an ear nose throat ENT doc, go to one, could be sinus related or an earache. But the first thing I thought of when you told your story, DESPITE the negative neck X-ray, is that you have wrenched your neck badly and a compressed or damaged nerve is doing this to you, so you may wish to have a CAT scan of your spine to make sure everything is where it's supposed to be in your neck.
