<s>[INST] I have had burning mouth syndrome and burning in other mucous membranes. Are they related? I got this 9 years ago. It is so painful and it had subsided but started up again very suddenly 2 weeks ago. Is there any new information you could give me regarding treatment? [/INST] Thanks for using Health Care Magic.Read your query.Burning mouth sensation as you have mentioned is usually of unknown cause, though some conditions like severe vitamin deficiency, stress ,dry mouth, diabetes , GERD ,allergies can aggravate the condition.I would advice you to get a complete blood profile to rule out any systemic conditions like diabetes, thyroid,nutritional deficiencies and get them treated.Drink lots of fluids and keep hydrated,avoid carbonated drinks .Avoid alcohol and reduce stress.Hope this was useful.Thanks and regards. </s>
