Thanks for writing to us.
You are having parosmia
where your olfactory sensations are altered. This commonly happens due to chronic cold
, allergic rhinitis
or Vitamin B12 deficiency
You can take steam inhalation and Vitamin B complex supplements for 2 weeks and see if your symptoms improve. In case the problm is persistent, getting an ENT evaluation done will be helpful.
I hope this information has been both informative and helpful for you.
