Hi, has anyone who has been treated with radiation therapy for head or neck cancer experienced phantosmia, or smelling something that is not there? For about the last 2 months I’ve smelled a musty kind of burnt smell off and on throughout the day – sometimes for only a few minutes other times for several hours. I’ve not lost my regular sense of smell. My last radiation treatment was in June 2015. My radiation oncologist has referred me to a neurologist who says it could be nothing and go away on its own (or not), or may be something more serious, eg, polyps, nerve damage, brain tumor. I’m scheduled for an EEG and MRI and hope to learn more after those tests. In the meantime I’m curious if anyone else has experienced olfactory hallucinations. Thank you.
