Smelling things that aren't there is called phantosmia. It can be unpleasant and affect how things taste. But it isn't usually serious and may go away by itself in a few weeks or months. See your GP if the strange smell doesn't go away in a few weeks.
Yes, anxiety and the stress it causes can cause many odd symptoms, including phantom and odd smells.
Conclusions: Stroke, angina, congestive heart failure, well-managed high blood pressure, and well-managed high cholesterol are associated with phantom odor perception. Vascular or metabolic conditions or their treatments may contribute to reporting of phantom odor perception.
But your symptoms may linger if a neurological issue is the cause. You should see a healthcare provider if phantom smells last for more than a few weeks.
a brain tumour in the temporal lobe could lead to sensations of strange smells (as well as other symptoms, such as, difficulty with hearing, speaking and memory loss)
Phantosmia may be caused by a head injury or upper respiratory infection. It can also be caused by aging, trauma, temporal lobe seizures, inflamed sinuses, brain tumors, certain medications and Parkinson's disease. Phantosmia can also result from COVID-19 infection.
Qualitative olfactory dysfunctions, such as parosmia and phantosmia, may be clinical conditions secondary to neurological diseases. The incidence of parosmia is underestimated, as well as its association with neurological diseases, due to poor self-reporting of patients and lack of objective methods for its measure.

Phantosmia and dysgeusia as the first presentation of glioblastoma.
Drug reaction: A person may need to stop taking the drug that may be causing the phantom smell. Potential medications that may cause phantosmia include antidepressants and antibiotics. However, a person should not stop taking such medications without first consulting with their doctor.
Can Smells Wake You Up? Smells do not usually cause a person to wake up.
In COVID-19 patients, the prevalence of phantosmia also fluctuates between studies, from 10% [15] to 34% when OD is still present up to 11 months after the acute phase of the disease [11].
Phantosmia has been clinically related to schizophrenia and mood disorders: these mental diseases and perception of phantom smells have been linked to abnormal levels of several neurotransmitters such as acetylcholine, dopamine, and norepinephrine (27).
Observation: About one-third of individuals with phantosmia will experience symptom improvement over time. Medications: Antipsychotics, antimigraine medicine, and antiseizure drugs can all be used to treat phantosmia. Surgery: Olfactory mucosa excision surgery may relieve phantosmia while preserving olfactory function.
Phantosmia is a qualitative olfactory disorder wherein an odorant is perceived in the absence of an identifiable stimulus. Although phantosmia is most often idiopathic, it may be associated with nasal mucosal abnormalities, migraines, seizures, and neurocognitive or mood disorders.
Interestingly, participants with diabetes treated with insulin showed a higher prevalence of phantom odours as compared with participants without diabetes (OR 2.98, 95% CI 1.41–6.32) [15].
However, some people experience a change to their sense of smell about three to four months following infection. People report certain things—like food or body odor—smelling like garbage, rotten eggs, or chemicals. This altered sense of smell is called parosmia.
Hallucinations of some kind are thought to occur in about 30%–40% of Parkinson's patients, with olfactory hallucinations, or the detection of phantom smells that are not really there, occurring in somewhere between 2.1%-11% of patients.
Fibromyalgia can also impact other senses, like how you see colors and your sense of smell. Some people even report strange smell sensations when there are no odors present.
It can occur in one nostril or both. Unpleasant phantosmia, cacosmia, is more common and is often described as smelling something that is burned, foul, spoiled, or rotten. Experiencing occasional phantom smells is normal and usually goes away on its own in time.
In fact, 1 out of every 15 people over the age of 40 reports having them. While aging is a common cause, phantom smells can be a sign of underlying medical conditions or endocrine disorders such as hypothyroidism.
