Can TOS cause chest pain and numbness in the arm?

Hello,

Welcome to icliniq.com.

I understand your concerns.

Thanks for sharing such a detailed history. It really sounds like you have been through a lot. Based on what you have described, thoracic outlet syndrome (TOS) could be a strong possibility, especially considering the recurring pain in your upper chest and back, along with numbness in your arm.

Here is a more focused breakdown to help make sense of it:

A. Why TOS might be the cause?

TOS occurs when the nerves, arteries, or veins in the thoracic outlet, the space between your collarbone and first rib, are compressed.

There are three main types:

1. Neurogenic TOS (most common): This involves compression of the brachial plexus. Symptoms include neck, shoulder, or upper chest pain; numbness or tingling in the arm, and sometimes weakness.
2. Venous TOS: This involves compression of the subclavian vein. Symptoms include swelling, discoloration, or pain in the arm, often after activity.
3. Arterial TOS (rarest): This involves compression of the subclavian artery. Symptoms include coldness, numbness, or color changes in the hand.

Given your symptoms, neurogenic TOS seems like the most likely type, if TOS is indeed the cause.

B. Other possibilities to consider:

There are a few overlapping or similar conditions that should also be ruled out:

1. Cervical disc herniation or radiculopathy.
2. Myofascial pain syndrome.
3. Costochondritis (especially for chest pain).
4. Pectoralis minor syndrome (can mimic or overlap with TOS).
5. Cardiac causes. Even if unlikely, especially if you are young, it is important not to dismiss them entirely.

C. Recommended next steps:

Since no conclusive tests have been done yet, and you have already seen multiple doctors.

Here are a few things that might help move this forward:

1. Ask for imaging: MRI (magnetic resonance imaging) of the cervical spine and brachial plexus to check for nerve compression. X-ray or CT (computed tomography) scan of the neck and shoulder area to look for cervical ribs or an abnormal first rib. Doppler ultrasound or venography if vascular symptoms (like swelling or discoloration) appear.
2. Consider physical or provocative tests: These are usually done by neurologists or physical therapists familiar with TOS, such as Adson’s test, Roos test, and Wright test.
3. See a neurologist or thoracic outlet specialist: A neurologist can perform EMG (electromyography) or NCS (nerve conduction studies) if needed. You might also consider a physiatrist or vascular surgeon with experience in TOS.
4. Get a physical therapy (PT) evaluation: A good physical therapist can guide you through targeted exercises, like postural correction, nerve glides, and stretches for the scalene and pectoral muscles. If your symptoms improve with PT, that is a strong indicator that TOS could be the culprit.

D. What can you track at home?

Start a simple symptom log to identify patterns.

Track:

1. When does the pain or numbness occur?
2. Triggers (specific arm positions, workouts, and sleep posture).
3. Duration and intensity of each episode.
4. What helps relieve it (heat, rest, and stretching)?

This kind of record can be incredibly useful for your next appointment and may help point toward (or rule out) TOS.

I hope this helps you.

Thank you.
