An olfactory hallucination (phantosmia) makes you detect smells that aren't really present in your environment. The odors detected in phantosmia vary from person to person and may be foul or pleasant. They can occur in one or both nostrils. The phantom smell may seem to always be present or it may come and go. I seem to be experiencing this for the last month. I had a breast biopsy, which fortunately was free of cancer. The minor wounds from the procedure were treated with a medical salve and bandaged. I can still smell the medical salve over a month later. I have googled this and know it can be the result of various medical conditions. But with my history and knowledge of TMS, I'm wondering if this could be related somehow. Anyone else ever experienced this?
