There is only a single photo but it does show that you have a small axilla and a narrow mouth. Coupled with your history of TMJ disorders, headaches and previous orthodontic relapse I suggest you strongly consider correcting the underlying problem of the narrow maxilla. This is associated wiith a narrow nasopharyngeal airway, forward head posture, snoring, UARS and Sleep Apnea dependiing on age. Definitely contributes to headaches and jaw issues.There is not a full smile picture but I assume you have dark buccal corridors and possibly dark circles under your eyes.You can address all of these issues with a DNA Appliance, Oral Myofunctional Therapy, oral myology and Mewing but Invisalign addresses noone and may make the TMJ issues worse.
