Dear patient, cold viruses always go around. normally this will go away within a week or 2. What you can do to treat it is inhalation of hot steam with salty water, nasal spray like xylometazoline, some mucus/phlegm solving medication like acetylcysteine, taking in a lot of fluid (tea and water is good, no sugary beverages since that support phlegm). For pain and high fever paracetamol or ibuprofene is advisable after checking for contraindications with your md. If this persists for more than 2 weeks there needs to be reevaluation about perscribing you an antibiotic for secundary bacterial complications. But in most cases antibiotics are not needed with viral upper respiratory infections. Hope this is helping you , if you have any clarificatons you can get back to me, if this was helpful please kindly rate my answer. Best regards
