What Are The Treatments For Parosmia Lasting Three Weeks?

Hi! I am sorry for bothering you at this time. I really needed help and I had no other choice but to contact you. I have about 3 weeks that I am dealing with parsomia, I cannot smell the taste of the food as it really is, and this issue is really making me feel bad. I would appreciate your help. I would like to know any solution or treatment that had to be done about this. I am waiting to hear from you. Best regards
