Is having surgery on the bone a possibility? Sometimes our bone structure and other genetic issues can make us more prone to sinus infections. Sounds like that is the case with you.
You get a cold, sinuses can't drain properly due to facial bone structure, then the mucus sits and becomes bacterial and then you have a secondary sinus infection needing antibiotics.
I would see if surgery is an option for this. good luck
Have you been tested for other breathing problems? I am frequently stuffy myself, and they said it was non-allergic vasomotor rhinitis. Also, I am pretty sure there are surgeries available for nasal bones. After all, if the nasal septum (divider between nostrils) can be surgically repaired, why not other bones? I would use tiger balm to clear a stuffy nose. Decongestants can give you rapid heartbeat and are as addictive as any other drugs, so try to only use those when you absolutely cannot breathe without them and tiger balm fails.
