i have sinus problems even when i get a cold my nose always remain dry?
well blocked nose is due to sinus congestion only. so my suggestion is to consult an otorhinolaryngologist and get evaluated. a pns view x ray can be done. a course of antibiotics anti-inflammatory painkillers decongestant nasal spray like xylometazoline saline nasal irrigation steam inhalation can relieve you. doing warm compresses​ around nose will help. use a humidifier in your room. avoid very cold atmosphere. hope this helps.
