10 days after septorhinoplasty -- will my sense of smell and taste ever be the same again?

Day 1 & 2 I could eat but it was bland. Day 3 I got a foul smell and taste instead of the foods real taste. Most sweet things like yogurt, fruit, toast aren't so bad but I haven't eaten a meal in a week. It all smells and tastes the exact same. can't be near food and cant walk through town without feeling sick at every smell including cigarettes, perfume so I can't socialise and I've lost a lot of weight already. took antibiotics for ulcers presumed tonsillitis on day 2 also. What's happening :(
