I get sinus infections regularly. would getting my tonsils removed help with this?

Unlikely: In children with chronic sinusitis, adenoidectomy can sometimes be very helpful. But while the adenoids are the cousins of the tonsils functionally, the tonsils are not removed for this issue. In adults, adenoids are typically no longer present as they shrink away with age, so that isn't a surgical option for sinusitis. And tonsillectomy is also not indicated for sinus issues in grownups.
