The suggestion of a neti pot is a very good one, used for many centuries, across many cultures. “Nasal irrigation” can be a preventive action as well as a means to deal with an existing problem. Much clinical research supports this notion. There are no harmful or negative side effects, either. Will help, can’t hurt. If this is an on-going issue for you, consider one of the newer versions of a neti pot, such as a Grossan Nasal Irrigation System as it is far superior to the neti pot and just may help you deal with what you know will be coming each season. Google “sinusitis” and thereafter, “nasal irrigation” for a wealth of information that may help you gain valuable information. Hope this helps, I’ve dealt with this for decades and nasal irrigation really helps me. A medical professional (Otolaryngology Specialist / ENT doctor) can help with an existing condition; and an Allergist may be needed to help ward off future problems.
