Veins Tingling, Hand/Legs Numbness.

I have been having this issue regularly from past 2 years. Every hour of the day, i have this weird tingling all over my body, sometimes its on left hand, sometimes its on left chest, sometimes my legs are numb and I feel restless (maybe because of overthinking). But if I am using phone now my left hand will have the tingling problem, like the veins are pumping, a little heaviness on the left chest. I am under no medications, done zero tests. I have a sinus issue of which I take care by wearing masks regularly, then from few months I have this acid reflux problem but that is it. I am looking to consult a right doctor or do the required tests for the problem but not sure who to see and what to do! I really want to solve this issue.
