Yes many of them.. check out the sticky threads above on TOS thread list page..

-Shortness of breath
-Neck pain most just left side

OH Yes!!! My top rib was stuck in raised position due to severe muscle spasms

If you read the thread just before yours I mention top rib mobilisation by expert PT & then by very good DC (after I told him about what the PT guy had done and how many symptoms had went away after) ) along with other things that can help..

It is not a quick fix condition, I went to DC a lot durign the worst of it, eventually tapered to once a month then every other month..plus all the home posture work & far infra red heating pad, IF stim and tennis ball trigger point work..
If working or doing problem activities it takes a lot longer..

Thank you for your response. I’m still figuring out how to navigate the site. I’m looking at sticky threads now. My chiropractor told me it takes time. I just haven’t felt any consistent improvement so I got to wondering if it’s possible other things are happening. Good to hear TOS can cause these things. Maybe I should check into PT also?

My chiro did PT type modalities also, massage, trigger point, ultrasound, IF stim, low level laser, plus the upper cervical (c1 c2) adjusting.

If yours dosen't do anything but adjust - then yes, search out an advanced PT for the best experience & knowledge..

The more you learn from the stickies will help you to decide if they are good or not..
Don't stay with anyone that is not helping, or makes you feel worse..

PT may help in addition to chiro, but getting an accurate diagnosis is important. You will most likely need a referral to PT, so start by seeing a doctor that specialized in TOS (often a thoracic surgeon). If you let us know what state you live in someone on this forum may be able to suggest a local doctor.

That’s my main thing. I just want to be positive that TOS is accurate diagnosis.
I live in Tennessee.

Also I have an appointment with a neurologist in mid July. Could that help get accurate diagnosis?

Often a TOS dx is a process of ruling out other things, then factoring in your sx..
TOS is a slow dx process.. Many MDs have partial knowledge if any.
They prefer something to clearly show up on testing or imaging.
For best results , find a well known TOS Doc..

Please read my droopy shoulder syndrome post and see if it could pertain to you. Best of luck in your recovery. I know your pain.
