Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain loss of sense of taste after severe cold is related to loss of sense of smell as both these senses are interrelated and as you have started getting back the sense of taste, gradually the sense of taste will also reverse and you need not to worry as it is a common finding in case of severe cold and sinusitis symptoms and will reverse gradually when the cold will subside.. You can do steam inhalations, saline nasal irrigations and decongestant nasal drops like Otrivin to open up the nasal passages and gradually you will be completely alright and you need not to worry about it at all.. Hope this information helps.. Thanks and regards. Dr. Honey Nandwani Arora.
