POTS? (i beg open if u have pots)

Hi! I might have pots?? tbh I'm not sure at all. I have Ehler Danlos Syndrome (EDS), a hypermobility disorder that is commonly seen alongside pots. More and more recently I've started to notice things in my daily life that remind me of pots (ex: My legs turn purple and go numb when I sit and my vision goes black when I stand up). Does anyone on here have pots?? If so when did you notice something was wrong/wanted to get diagnosed? I want advice to help because I'm currently having trouble with my ankles and my legs going numb so often is leading me to sprain my ankles multiple times a week. I'm a ballerina so this is not very cool :'].
