Can someone please help? Off and on Voice loss w/ Neck Pain for 9 months

[VoicelessInWV]

9 months...I'm finally throwing it out to the internet.  
In June 2020 I got a bout of laryngitis.  I continued on for 10 days w/ progressing neck pain radiating up to my temple on right side.  Sent for Covid test (neg). Worsened and went to ER.  Xrays and CTs showed slight protrusion of C4&5 and C6&7, but otherwise - normal. CBCs normal. SedRate/Inflammation marker - normal.  I am female, 5'8 140, overall good health.  In the last 9 months, ENT for laryrngoscopy -> clear.  No history of reflux, but sent to gastroenterologist (for possibility of LPR and I said that I had a habit of clearing my throat a lot?) and put on protonix and pepcid and eliminated host of foods. I've been put on cyclobenzaprine (5mg 3x/day). I've tried NSAIDS. No matter what I try, it continues to come and go.  The voice comes back, but it will go randomly and be gone for days (like now) - raspy, breathy.  

I do notice sternacleidomastoid (scm) being tender/sore, and up under jaw, behind ear, in ear, in rt lymph node area especially behind it, but lymph node not swollen, but just in that area.  I know the scm attaches in tha region, and there are a host of neck muscles, and even under chin in diagastric muscles, plus shoulder &n neck muscles that can come into play here.  My trapezius muscles are often sore (after chores, dishes, walking dog,etc) as well.  

So can this be an issue with my scm? I am aware of muscle tension dysphonia, but my voice comes back and the scm stays tense. I do have a history of anxiety & holding tension in my neck and back, but it's almost as if it never goes away now even when I'm relaxed and the scm area always feels weird at the top few inches of that muscle, under the ear.  Can you have tension that stays regardless of muscle relaxers (eg. hyperstimulated muscles)? Could my hyoid or larynx be affected by my scm being strained?  Could I have permanently injured that muscle? What kind of specialist would I even see at this point?  Neuro/Ortho?  In an area where there aren't a lot of choices of specialists in this area so looking for any advice or feedback.  I don't know what else to do.
