Chronic myalgia/muscle pain. What tests to get?

I used finasteride years back. In hindsight it gave me some neck pain that went away upon discontinued use, but a few months later I developed chronic muscle - specifically myofascial pain that has persisted until this day.

I am wondering what tests I should get? From a search I came up with:

  • cortisol
  • creatine kinase
  • aldolase

I have already gotten testosterone and TSH/t3/t4, all of which came back fine. I also got dhea and estrogen recently and I’m awaiting the results. There is no test for DHT where I live.

Anything else?
