Thoracic outlet syndrome causes arm pain, numbness, and weakness from nerve and blood vessel compression in the neck and chest. Chiropractic care at Pura Vida addresses the structural causes of this compression.
Thoracic outlet syndrome (TOS) involves compression of the nerves (brachial plexus), arteries, or veins as they pass through the thoracic outlet — the space between the collarbone and the first rib. Neurogenic TOS (the most common type) compresses the brachial plexus, causing arm pain, numbness, and weakness. Compression can occur at three anatomical sites: the scalene triangle (between anterior and middle scalene muscles), the costoclavicular space (between the clavicle and first rib), and the subcoracoid space (beneath the pectoralis minor). Poor posture, forward head position, and first rib subluxation are primary contributors. Chiropractic correction of these structural factors is central to TOS management.
Dr. Foss addresses TOS through first rib adjustments — correcting the elevated or anteriorly displaced first rib that narrows the costoclavicular space. Upper cervical and thoracic corrections reduce the tension in the scalene muscles that compress the brachial plexus at the scalene triangle. Soft-tissue release targeting the pectoralis minor and scalene muscles further decompresses the neurovascular structures. Forward head posture and rounded shoulder corrections eliminate the postural component. Most TOS patients experience significant symptom reduction within a structured course of chiropractic care.
At Pura Vida Chiropractic, Dr. Foss uses Sacro-Occipital Technique (SOT) — a gentle, category-based system that addresses the spine, pelvis, and craniosacral rhythm as one integrated unit. SOT restores proper biomechanics, reduces nerve interference, and creates the neurological environment your body needs to heal itself.
For many patients, combining spinal correction with regenerative therapies produces faster and more lasting results. Depending on your condition, Dr. Foss may incorporate one or more of the following:
Patented unfocused shock waves spread over a broad treatment area to reduce inflammation, increase blood flow, and activate stem cells — promoting cellular regeneration and long-term pain relief.
Photobiomodulation with a 10–15W Class IV laser delivers therapeutic light energy deep into tissue, reducing inflammation, blocking pain signals, and speeding healing at the cellular level.

Dr. Dan Foss is trained in Sacro-Occipital Technique (SOT), a comprehensive chiropractic system that addresses the whole body — not just the area of pain.

TOS involves compression of the brachial plexus, subclavian artery, or subclavian vein as they pass through the thoracic outlet between the clavicle, first rib, and scalene muscles. Drivers include scalene hypertonicity, first-rib elevation, forward head posture, prior trauma, and rarely an anatomical anomaly (cervical rib, fibrous band).
Dr. Foss addresses the three most chiropractically responsive contributors: first-rib elevation (specific gentle adjustment), scalene hypertonicity (manual release work), and forward head posture (postural correction and SOT cervical work). SoftWave therapy reduces chronic scalene inflammation. Many TOS patients avoid surgery with conservative care.
Most TOS patients see meaningful improvement within 8–14 visits over 5–8 weeks. Stable resolution typically develops over 16–24 visits across 3–4 months. Cases with vascular compression or significant neurological deficits may require surgical consultation.
Yes, with appropriate technique. SOT and the specific first-rib correction Dr. Foss uses are low-force and well-tolerated. Dr. Foss screens for vascular TOS (subclavian artery/vein involvement) warranting vascular surgery consultation before initiating conservative care.
