https://akhalikov.blogspot.com/2021/10/sinus-pressure-blocks-nasal-passages.html I also noticed blockage in office workers who do the 8-12 hour brain work and sometimes they push their mind into extreme. So, it is not just an allergy, but common problem for brain stressers. If you want to see some case, please go to youtube and listen for teachers of programming classes. Most of them have stuffy nose while presenting their lessons  :-)  Not really funny though. Also, check this out:  Sinus Issues May Be Linked to Anxiety and Depression

Idea: May be the installation of some permanent implants with micro holes to relieve the pressure(liquid) would help? Does Spray (Oxymetazoline makers, multi-billion business) preventing human to achieve this? Must be as small as possible and multiple implants!
