im an 19 year old female and I live a very sedentary life due to recently being diagnosed with low bp and inappropriate sinus tachycardia and it scares the crap out of me when I stand and my hr shoots up, but anyway, 90% of the time I’m sitting or laying down. Sometimes when I stand for too long my legs will turn purple with white spots and itch, since I started getting so scared of DVT I convinced myself that I must get up more. So yesterday I was up a lot trying to keep the blood moving and right before bed I had chest pains on the left side next to my breast, but I made myself go to sleep and I woke up this morning with sligh aching in the same place in my chest but put it off then throughout the day as I was standing from my hip down to the back of my knee was aching, not serious pain just a little ache and I’ve had about a million anxiety attacks today about it but my mom keeps telling me there is no way I have it because there is no warmth or swelling or redness. Just a little pain. My mom pushed my foot forward to see if it’d hurt behind my knee and it did but it hurt the same in the right leg. I don’t know if I’m just freaking out or if it’s legit.
