Should I Do Tilt Table Test?

I have this condition since July. Poor man's tilt table test positive.

But my HR isn’t very annoying. I feel tired and etc, but stomach issues (I don’t know maybe gastroparesis) and headache (continues migraines for 3 months) are the worst. My resting HR 70-80, standing 110+-, walking 100. I have never fainted or something.

I read that TTT can worsen your symptoms and now I’m thinking should I do it? I’m not going to take any meds for it at least now. Can TTT worsen the symptoms, what’s the point to do it?
