I have had this green, sticky, and smelly snot for almost a year now. I had a deviated septum surgery years back, any idea as to the problem?
Sinusitis? You still may have difficulties with the sinuses that is contributing to the green smelly snot. This will likely require further evaluation and possible treatment.
Green snot. Green sticky and smelly snot almost always means some sort of ongoing infection. You could have polyps. Even though you had septum surgery, the infection could be in one of the sinuses. Please see an ENT surgeon. Talk to your md about getting an MRI done to look at the sinuses.
