Well, when I had a sinus headache I called my doctors office or the OB Triage Department at my hospital. But I took over the counter Clairtin and Benedryl. But more martial remedies are tea, a hot towel over your head and face and the internet has good tips on natural remedies on sinus headaches.
I used to pack up and go see my chiropractor My chiropractor knew an adjustment that helped sinuses. Be ware though that that adjustment will turn on the nose faucets so keep some tissues nearby.
I was told you could see a chiropractor all the way up through til delivery day and it was safe..you just cant have an adjustment done lying on your stomach at this point. Always call to make sure they are trained in OB care as well . Hope that helps
