Really strong pulse in fingertips and fe

I have anxiety disorder recently my symptoms have gotten a little worse i get tingling in hands now, stomach pains and burning, elbow and back pains, shortness of breath.Recently i have been sweating way too much at times my hands, feet and forehead. I also sense really strong pulse in my hands to my fingertips and feet its in the bottom left of the feet that entire part pulses with the pulse while lying down.I have had numerous ecgs, echos, stress tests came back normal.I have POTS aswell my heart beats really hard while just walking around.I also have raynauds syndrome but the worst part is it happens all over my body leaving red patches after it stops it feels like burning pins hitting my skin was limited to hands now its entire body i have bleeding gums aswell and recently for some reason my wisdom tooth started hurting every time i was eating or putting pressure against it after alot of stress the pain lasted for few hrs which doesn't make any sense.Please let me know what i do?
