Is smelling smoke a symptom of a brain tumor a myth? had ct scan 2 years ago for phantom smells. everything normal. now constant smell of smoke x2 days. dry sinuses? no other neuro symptoms.

Rarely caused by...: Your condition is called phantosmia. While brain tumors can cause it, that's an unusual cause. I advise having neurologist re-evaluate. I'm unaware of research on how to treat this but some have success with Gabapentin ; other meds for epilepsy- see http://chemse.Oxfordjournals.Org/content/27/7/611.Full when western medicine doesn't have answers consider homeopathy ; chinese medicine/acupuncture.

See your PCP: Myth, or no myth, it warrants further investigation. Smelling unusual smells that aren't present like smoke is not normal. So the first person to start a dialogue with is your pcp. S/he will be able to advise you further, and provide a referral to see a neurologist, if that's needed. Right now it needs to be documented, especially if you're smelling it full-time.
