Hello and welcome to NeuroTalk. I'm so sorry to hear about the pain you're experiencing. I wish I had an answer for you. My first guess would have been neuralgia but if your neuro says that's not it then I'm not sure what it could be. Could it be a side effect from a med that you're currently taking? Could it be some form of Bells Palsy? Hopefully someone will come along here shortly and be able to help. In the meantime, welcome to the site. Sorry for your reasons for being here but glad we have the opportunity to try and help.
