Thanks for asking!

POTS is short for postural orthostatic tachycardia syndrome. It's a chronic illness that is most Known for causing people to feel light headed/dizzy, sometimes to the point of passing out, when going from sitting or laying down to standing or from standing to long (sometimes only for minutes). For example, all last week when I got up in the morning and I was standing getting ready, my heart started racing, it went up to 130 bpm, and I felt really hot like I was going to pass out. I also have to sit when teaching because standing will make me feel light headed.

A few other symptoms I get are headaches, nausea, heat intolerance, and extreme fatigue/body weakness but there are a lot of other symptoms that POTS can cause too.

In my case, it seems to have been caused by whatever made me super sick last November (maybe a virus?).
