I had sinus surgery and that helped a lot.

Have you tried chiropractic? One time I went when I was in so much sinus pain and pressure and there was a dramatic release once I was adjusted.

Benadryl is sometimes super helpful during attacks. Our ER here in red deer gives a combo of benadryl, gravol and tordal through intravenous when migraine patients end up in emerg. Dramatically takes the edge off for sure.

Carol, I too got put on montkelustat ... About year & half ago ... I think it helps make them less
Severe ...hope it helps you too.

I have Rhinitus 24/7 with sinus pain even though my sinuses are perfectly clear. I've just been prescribed Montelukast which my Dr said could take upto 3 months to start working. Elderberry eh?
