Welcome @Rex! I’m glad you’re here. Thank you for posting some of your images. I removed your name & birthdate from them to protect your privacy. I’m sorry you’ve lost your job due to the medical issues you have going on. Hopefully once your styloids & are shortened/IJV(s) decompressed, the TOS is dealt with & you’ve healed, you can go back to work if you choose to.
The first thing that jumped out to me are the two halves of your C1 appear to be disconnected from each other. I Googled this & read that "congenital anomalies of the posterior arch of C1 are relatively common & usually asymptomatic. (Congenital anomalies of the posterior atlas arch | Radiology Reference Article | Radiopaedia.org) . I wonder if the crazy overgrowth of your left PT is related to the anomaly of your posterior arch?
Your right styloid is spectacularly long. Your left one is looks pretty nasty, too! You weren’t joking when you mentioned the appearance of your left C1 TP!! WOW!! I can see the distention of your IJVs lower down which may be related to your TOS diagnosis (have you had surgery for TOS?). Your right IJV looks like it may be suffering some compression between your styloid & C1 but the left one (in spite of the crazy C1 TP looks ok to me - NOT a doctor here.).
Your cervical spine overall is slightly curved to the left & appears to have lost its lordotic curve (see pic #5). We have quite a number of members whose cervical spines are straight. The curve can be restored w/ gentle exercises that open the chest & help pull the shoulders down & back, & strengthen the neck’s extensors. When the cervical spine is straight, it brings the styloids into closer contact w/ the nerves & vascular tissues in the neck.
Here’s a good post that has good info about neck anatomy & exercises to restore the lordotic curve.
I’m really glad you’ve reached out to both Dr. Hepworth & Dr. Nakaji. I expect one of them will be able/willing to help you. Please keep us updated as to how your appointments go once you get them.
