Any medical professionals that can help diagnose this for me please?

I got a lab test back that says I have high CK, low vitamin D, low ferratin, low PTH intact. In pain a lot on and off, it started in June only in the chest, but now is constant in the feet, toes, hands, legs. It feels like nerve damage honestly I’ve considered MS, fibromyalgia, etc. Doctors haven’t been helpful in figuring out what it is and dismiss it as in my head or anxiety related. Let me know if you need more info but I’d really like any thoughts from anyone in the medical community or familiar with any of these symptoms altogether!
