Hi Sam and welcome.. To answer your above question-Yep... Good that you found the ginger. I use a mixture of turmeric, ginger and turmerones which helps a good deal.
It goes away sometimes and comes back sometimes
I have never used it but have read a few similar things. Unfortunately most of what I have read has been on the not so helpful side.
Maybe get an appointment with a ENT Doc. could be sinus related
I would start with the D3 ASAP! It has helped so many of us!
