Freaked Out by Sudden Venous/Circulation Issues

A little freaked out by how quickly and intensely I’ve had venous/circulation issues arise recently? I have been experiencing all sorts of chronic symptoms that fall under a typical EDS umbrella since I had covid in January, but then two weeks ago I looked down as I was taking a shower and discovered that the color of my legs was split directly in half w/ the outer halves being very mottled and bluish and the inner looking normal. Since then, it’s advanced so much. I can’t hold up my phone for more than a few minutes until my hands go completely cold. It’s like the coldness and pins-and-needles is just their constant state now. 24/7 it’s happening at least somewhere. I haven’t been diagnosed yet but from research it seems like POTS to me? Anyways - really alarmed and confused by how randomly it was brought on and how quickly it progressed to being a constant… This isn’t a question oops, just looking for support or similar experiences or info I guess?
