Heads up to readers: Before diving into the text below, I want to be absolutely clear that I am not suggesting anyone who experiences similar physical stress patterns or muscle tension instantly assume they have Hashimoto's or a specific endocrine condition. We are all biologically unique, and my personal medical outcome belongs to my own history. What I am highlighting is that being able to identify, map, and decode the unique ways your own body holds tension and stress is an incredibly powerful, transformative gateway into truly understanding oneself. It shifts us from fighting our bodies to cooperating with them.
Following a stunning, deeply resonant discussion on this forum recently—and with a huge nod of gratitude to Alexa from a prior discussion and the other brilliant contributors on that and other - including those who have talked on this same topic before in their own unique ways. — I’ve been thinking a lot about how our physical bodies map out the trauma of chronic masking. Alexa’s framing of a post-diagnosis lens as a singular "medicine"—a neutral vocabulary that sweeps away a hundred disparate explanations of individual "failures"—has directly catalyzed a major breakthrough in how I examine my own physical and psychological landscape. It has forced me to look deeply at the role of interoception in how we reclaim our context.
Interoception—our conscious and unconscious awareness of internal bodily sensations, from heart rate and muscle tension to visceral discomfort—is something many of us in the autistic community experience uniquely [NAS Professional Practice Hub]. As the National Autistic Society Guide on Interoception and Wellbeing notes, a significant percentage of autistic adults experience atypical interoceptive awareness, making it difficult to process internal signals before they reach an absolute crisis threshold [NAS Professional Practice Hub]. In our previous discussions, many of you shared incredibly familiar patterns, noting how chronic masking and intense situational stress manifest as deep, persistent shoulder and neck tension. We often carry the weight of neurotypical performance parameters directly in our muscles.
For a long time, my own interoceptive tracking was a source of profound confusion. I was experiencing severe, volatile physical symptoms: a sharp, restrictive "catch" of pain beneath my right floating ribs that radiated into my shoulder blade, accompanied by heavy executive paralysis. Falling into a classic trap of hindsight, I tried to analyze these signals as completely isolated issues. I explained the physical pain as a simple localized muscle strain, and the cognitive flatline as a personal failure to cope with intense, ongoing situational trauma and institutional duress.
However, when I stopped viewing these signals as chaotic, noisy failures of my body and started looking at them through an analytical, autistic lens, a profound classical mirror clicked into place: the myth of Prometheus.
In the ancient text, Prometheus is chained to a rock of unyielding situational duress, where an eagle arrives to systematically consume his liver every single day, only for it to regenerate in the quiet stasis of the night, setting the stage for the cycle of retribution to begin anew the moment he wakes.
By utilizing my interoception not just to feel the pain, but to map its precise temporal and mechanical patterns, I realized my body was living out that exact diurnal Promethean loop. I began tracking the data my body was sending me with absolute precision:
- The Night Stasis: I noticed that during the night, as my body remained immobile in a fasting state, internal physiological stress quietly built up, causing my rib muscles to tighten into a hyper-tonic, protective shell.
- The Morning Retribution: I registered that the exact moment of waking—when the autonomic nervous system releases a natural surge of hormones to jumpstart morning activity—the internal tension peaked. My descending diaphragm physically compressed the underlying tissues, triggering a sudden, stabbing muscular guarding response under my ribs. The morning waking was when the physical debt of my background environmental trauma was being collected.
- The Dynamic Shift: My interoception showed me that this wasn't a static, structural break. The pain fluctuated. Movement, warmth, and conscious somatic down-regulation could cause the guarding to temporarily ease into a "valley" of relief. Yet, a sudden mechanical jar (like a vertical heel strike during gait), a deep breath, or a fresh spike in background situational stress instantly re-facilitates the loop, causing a sharp return of the protective guarding.
I had spent years believing my body was simply "breaking" under chronic stress. However, by leaning into my autistic capacity for pattern recognition and decoding these precise interoceptive signals, I refused to let the symptoms be dismissed as purely psychological. This internal data gave me the specific clues needed to confidently request targeted blood panels from my medical team. By advocating for myself based on the physical data my body was sending me, I was able to secure the right testing—specifically an antibody check—to formally identify the root cause as Hashimoto's thyroiditis.
The puzzle completely solved itself. I realized my system was operating within a highly predictable, unified physiological feedback loop where chronic external trauma was unmasking an underlying, active autoimmune vulnerability.
Decoding this internal data has been the ultimate act of reclaiming my context. It proved to me that the physical "catch" under my ribs and the executive flatline were not personal failures, unmanageable psychological deficits, or hypochondria; they were the literal, biological wear-and-tear of forcing an autistic nervous system to perform under prolonged trauma. As documented in the National Autistic Society Guide to Autistic Fatigue and Burnout, deep exhaustion from sustained cognitive and environmental overload frequently manifests as acute physical pain and systemic loss of function [NAS Guide to Autistic Fatigue].
When we open our past experiences for examination, active hope becomes the fuel that lets us rebuild. By learning to accurately decode our interoceptive signals rather than tuning them out or misinterpreting them as isolated failures, we can give ourselves a single, neutral explanation that replaces a dozen painful self-blames. We stop trying to fight individual physical symptoms and instead start altering our environment to protect our biological baseline.
Building on the shoulder and neck tension patterns Alexa and others have previously discussed, I would love to open this up to see what we have found within our own bodies and how we have gone about accommodating it:
- Where does your body typically hold or map stress (e.g., neck, jaw, shoulders, respiratory pacing), and when does that tension predictably peak or quiet down?
- How did you move past viewing that physical sensation as an isolated strain, and realize it was an active somatic mirror of masking or autistic burnout?
- What environmental adjustments, pacing strategies, or communication modifications have you found helpful to naturally lower your baseline stress and accommodate your body's energy levels?
