I Have hear t.n. coming from RSD , MS and also heard of Trigeminal Neuropathy as opposed to Trigeminal Neuralgia. I haven't had mine start the way you have mentioned , mine is from sever face trauma . to me chronic nerve pain neuropathic or neuralgia .. it may have different names but it is the same. It is a monster . sorry to hear you are getting flare ups in your face. hopefully the meds will help control it. call your doc and Inquire about the new symptoms they may have an idea about some options and if it is t.n. or another type of pain.
sending positive energy low pain and hope you have a good night.
PEACE
