Rather than write you a book here, I would simply encourage you that your ability to self diagnose may be your biggest asset.
My definition of self diagnosis is being a life long learner (all sources) about your concerns.
Be unafraid to adapt as your body changes and as you learn and try new things.
Even though we usually question what we read, what we think, what we are trying, etc., our efforts at this build in us self confidence, foundational to the success of any treatment(s) we apply.
Help from all directions should be considered, but you are a very valuable source of information about yourself.
Trust that person.
