Thanks for choosing health care magic for posting your query.
I have gone through your question in detail.
To some exetent , yes you need to get investigated. But there is no need to panic at this stage. Olfactory hallucinations
, smelling something which doesnt exist , and an altered or heightened sense of smell suggests some intracranial pathology which is compressing olfactory area. but then there are other various causes for it including local nasal causes as well. So please dont panic but get a CT scan
of Head done ones to rule out anything serious.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
