Unlikely. The most likely answer is that your sinuses never drained and you had a secondary infection.

But it's possible that leaky blood vessels had some effect. Note that leaky vessels are very different from an actual bleed.

A sinus headache is distinguishable from a regular headache, so I wouldn't discount the leaky blood vessels possibility.

Good point pointing out the difference between a "leak" and a "bleed," though: if your brain is bleeding, that's a full-blown emergency.

Just a tiny little bleed 🥺
