The diagnosis of Burning Mouth Syndrome is hard to get and spend lots of time to reach that diagnosis, because the disease is not well known by doctors, even by specialists.
There being no damage to tongue and oral mucosa, or lack of saliva or salivary gland damage complicates the diagnosis. Because they are only the symptoms that the patient reports having no apparent cause. Dentists are the ones who are more familiar with this syndrome, however, most do not know.
Diagnosis was reached after many attempts at medical visits and drug solution, to find a doctor who knows this syndrome. Although this condition is more common than you think, (from 5% to 10% of the population suffers) the fear of the patient to be diagnosed with cancer, prevents medical visit.
The syndrome is treated as neuropathy, which is more common in diabetics.
