I did have a lot of issues with sinus area and teeth/gums, I was not stuffed up like a cold.
It was pressure, soreness and my throat would feel like I wouldn't be able to swallow. Tingling, numbness in lips tongue too.
It did get better and go away with in about 4 months of treatment and then only a small occurrence during a herx about 12 months into treatment.
I,m at a year and a half now and haven't had it occur since then.
