Smell most probably will come back, if there is no other abnormality.
You must get your nose examined by ENT specialist
Normally one side of nose is blocked in comparison to the other this is because of the nasal cycle
which is continuously going on inside the nose , to maintain the functional aspect of nose ,this is gods creation.
Do not get worried you can have steam inhalations so that if there is any congestion then it will clear up.
Or if you feel its more then you can use nasal decongestant drops ,but use then after consultation ,for few days only like 5-7days.
