correlation is not necessarily causation (look it up) – again: consult a good physician, get a second or even third opinion from educated abd experienced medical experts, but don't try to 'investigate yourself', because specialized knowledge and experience are required to correctly interpret the information.

I have specialized knowledge. Calculus 2, statistics, then econometrics, and then i taught. I can read the data. And having this specialization, I can tell you : you don't need it. Anyone can figure it out of they just try. But since you think credentials matter, I have plenty.
You've made some silly assumptions.
