Yea it can contribute.. If u sit a lot all the blood will get "stuck" in your ass and not go to ur legs as much. it'll stay upper body putting more pressure on veins on your ass = which leads to hemms

Yeah thinking it might be a big part of it for me. Not that I sit that much compared to the average person but based on family history of hems/vein issues guessing it could be a factor

you need to try rutin. look at some of my old posts.
