Just diagnosed with trigerminal neuralgia yesterday. Left lymph node under ear slightly swollen since late August (almost 4 months). Then I got a root canal done on back left lower molar. Pain medication included ultracet (tramadol), Norco (5/325), and tylenol 3 with codeine. Initially the pain in my jaw was intermittent, but within the past two weeks it has been a constant burn near where the root canal was done. My endodontist claims the root canal was flawless, so does my General dentist. My primary care physician basically stated that the CT scan they did shows minimal swelling of the lymph node and no sign of an abscess or cancer. From what I've read, TN is typically a sharp, sudden, 'electrical' type of pain. What I'm feeling is a fairly constant burning sensation, and a dull, constant ache, that seems only helped with Norco (and minimally at that) My PCP gave me a prescription for Tegretol, 200mg x 4 times per day. I'm only on the second dose of the first day and not really noticing any improvement. My doctor did say it could take 10 days to 'kick in.'
I'm worried about a few things: the first being the possibility of discontinuation syndrome, given the needed buildup in the system for it to work. The second is: the warning of depressive/suicidal ideation with tegretol use. I have a history of major depressive disorder. Finally, what if this turns out not to be TN and I was misdiagnosed? Any comments would be appreciated.
