question: My son has been suffering from jaw pain near jaw tooth and around nose, under eye. For a couple of days. He has been holding water(room temp) in his mouth to help alleviate pain.   He said as soon as he spits the water out it starts hurting. Last night finally became unbearable and went to ER.  They told him it was trigeminal  neuralgia. Prescribed gabbapentin for nerve and tramadol for pain and inflammation.  I've been wondering and thinking it was from a tooth. What do u think?
