I’ve been getting this almost every Spring. Big time sinus problems brought on by bad allergies. If phlegm is colored ask doc to do nasal culture to determine if there is bacterial growth. An ENT has special equipment to see up into sinuses and is the best doc to take an accurate nasal culture. If no infection I recommend: nasal rinses 2 - 3x day (used distilled or boiled water that’s been cooled to room temp - NEVER use tap water to do this), take muscus thinner (Musinex), gargling with salt water. Ask doc if antihistamines or decongestants would help. Sometimes they help but other times can make it worse. 4951
My husband and I had got something 2 weeks ago that was like allergies, but it seemed like I caught it from him. Either way it was gone in a couple of days and neither of us missed work. 4951
