[|Human|] My dad has been suffering from being light headed, this starts off with a pain in his mouth, this pain spreads up his face, making his nose run and then leaving him light headed. Doctors said it was a tooth ache, he has been to the dentist and they have said they don t know what it is. Any idea?
[|AI|]  Hello, Thanks for consulting Chat Doctor, Read your query, as your dad has headache, running nose this can be due to toothache, maybe there is carious tooth, painful and swollen gums, or pain can be due to sinusitis also. For this I will suggest you to consult oral medicine specialist and go for proper diagnosis of oral cavity, if this pain is due to tooth related then go for its treatment and if pain is not related to tooth then consult ENT specialist that pain might be related to sinus. Hope it will help you.  Wishing you good health. Regards,
