Fast Heartrate, Dizziness, Limbs falling Asleep Quickly

[UnderTrash]

I have been having a fast heart rate for the past month now, and at first it had been simply whenever I moved around even a little, as time went on, it became whenever I was around heat or had something hot to either eat or drink. Along with this, I would also become very shaky and sweaty. I have also noticed that my limbs would fall asleep quickly even if I wasn't sitting on them or blocking blood flow. I have also been having dizzy spells, with the worst resulting in me falling over sideways, though remaining conscious.
