Look into Orthotropics and Mewing. Oral posture does wonders. The jaws should grow forward, not be retracted by braces and extractions. There should be enough airway space. Look for airway-focused dentists for treatment.
I relate to this story. However, after several years, I figured the inflamed tonsils were just a side-effect of other issues. Check if you have postnasal drip, a deviated septum, or a nasal polyp. Several related chronic issues may also cause it.
Sadly, tonsillectomies on adults are actually quite complex and dangerous, but as a chronic tonsil sufferer, i assure you, removing them would not be a placebo. And every year, i have a week when i check hourly whether Laser tonsil ablation is available and approved in USA yet.
