Hello,
Usually thick green snot can indicate an infection, However, if you have seasonal allergies that can trigger it.
You could try nasal spray over the counter and guiafenisen DM the maximum amount also over the counter - also known as mucinex DM. IF that does not work in a couple of days then see your provider.
Remember to increase your fluids!
