I have tightness in my chest and shortness of breath usually 3-4 times a day. I was just diagnosed with pots but am really worried that this is something wrong with my heart. I am only 32 and have been sick with undiagnosed vertigo for 7 years now. I just developed this fast heartrate and chest tightness and shortness of breath, does anyone know if these are symptoms of POTS>
