@jasmine98 , I’m sorry I can’t recommend any specific treatment. No doctor helped me. I suppose it was time. I eat a healthy diet and work out daily. I try to keep my blood sugar managed. I get labs to monitor my overall health……so, I have no idea what caused it and why it’s improved. Most doctors gave me no hope of improvement. I think this is because they suspect the olfactory nerves are damaged and they don’t think they can repair.
