Lichen planus creates inflammatory patches on skin, mouth, or other tissues when immune reconnaissance teams mistake your own cells for invaders. This autoimmune response involves T-cell attack squads that infiltrate the basal layer of skin or mucous membranes, destroying keratinocyte teams that build protective barriers. The result: purple-pink papules (bumps), lacy white patterns in the mouth, or itchy plaques on skin. The exact trigger remains unclear—possibly viral infections that confuse immune training, genetic predispositions in cell-recognition systems, or medications that alter immune surveillance patterns. Stress can amplify immune overreactions. The "organism as team" framework helps you understand this as friendly fire—your defense teams received faulty intelligence and now attack loyal tissue-building crews. Your approach becomes recalibration: corticosteroids calm overactive immune troops, stress management reduces false alarm signals, avoiding irritants (alcohol-based mouthwashes, harsh soaps) protects vulnerable tissue teams, and immune-modulating treatments retrain recognition systems. You're not betraying yourself—your security teams simply need updated threat databases to distinguish friend from foe. This reframes guilt into a technical coordination project. ⚕️ This protocol does not replace professional consultation.
