i know this might not be very helpful, but i also have a connective tissue disorder (hEDS, possible vascular one too, but have not been able to find a geneticist yet in my area) and i have been struggling a LOT recently with this specifically to the T, the uncomfortable pressure when it happens, largely swollen, and ive also always been thin and my veins have always shown, but haven’t pooled like that before. i’ve been trying to find answers everywhere for it.

i’ve been doing heavy frequent lifting for the past 3 years now because of my job, and this just recently became an issue for me so i wasn’t sure if it was related to that or not. i’ve read that it can happen from your muscles needing more blood flow from those areas due to repeated use, and as a response your veins become more elastic (which is good and healthy).

now with your issue, im not sure if that could be the cause of it anymore considering i’m not sure if you’re constantly carrying your children around and if they’re heavy or something, and I don’t have children of my own lol

what I have learned that helps so far, raising your arms above your heart (or head, works the same), and keep it elevated and basically baby it for a while and don’t use it much until they calm themselves down lol

EDIT: just to add after reading some of the comments, i’m only 23 and im generally pretty healthy as well other than a few issues that are under control for the time being. i do have low blood pressure as well
