My doctor used a cannula and made multiple injections under my eye to fill that area and there was one point where he injected and it felt like it went deep and I yelped from the pain; it was exactly where my sinuses are. I felt a shooting pain in the back of my head. Is it not possible that by mistake he injected too deep and somehow it went into my sinuses? I’ve had sinus issues and swelling around my eye ever since, and I don’t usually have sinus issues. It WAS cold and rainy that weekend
