desperate for diagnostics

Hey there,
I’ve been suffering from chronic pain episodes for the past 5 or so years, progressively more frequent and increased severity. The pain that I experience is somewhat like what I have read on atypical trigeminal neuralgia. About 4 or so years ago I started feeling an intense jaw and neck muscle tightening, which I was then diagnosed with TMJD (tempro mandibular joint disorder) however; I used their prescribed mouth guards and NTI devices, which did not help me in the least. I then began feeling severe pains and tightening throughout my neck (from brain stem to base) and down into my shoulder blade, similar to charley horse, I suppose. It is a visually obvious balling of my muscle tissue. Frequent chiropractic visits gave me some hope and temporarily seemed to alleviate some symptoms, but not for long. During this time the pain spread throughout my face, down my jaw line and up into what I believed to be sinus area. There would be periods of time where I would be affected only by mild pains. Typically at this point my pain primarily resided on the right side of my body. Soon thereafter I started experiencing intense migraine-like headaches in the face lower jaw and eye orbit. Feeling like my eye itself is swollen and bulging. The pain episodes last for days in constant agony. My primary physician prescribed hydrocodone which does help alleviate a majority of the pain. In the past 6 months my pain has spread down to my elbow and wrist and even the tiny joints in my hands, but no longer does the pain reside on only my right side. It often times switches sides dramatically and without warning. I even feel joint pain in my hips, knee, and ankle now, I’ve been tested for arthritis but it came back negative. There are only brief periods of time now where I don’t experience severe pain. I'm only 23 years old. Every day for me is anxiety ridden about my pain attacks. It rules my life. It prevents me from functioning in society, not knowing whether normal activities are going to set off another attack. I’m in desperate need of some diagnosis. Atypical trigeminal neuralgia seems to encompass a lot of the symptoms I experience. Seeing as that's where all of this started for me, my face, jaw, eye, neck and mouth. I hope you can help me. I’ve been dealing with this for at least 5 years; everyday it gets worse.

Thank you very much for taking the time to read this
