[|Human|] I woke up with my left arm feeling congested. It doesn t hurt, but my veins are bulging, my arm and forearm have a red/purplish hue, and it feels slightly swollen. I can tell there is an area beneath my clavicle that is tight or knotted up and I m wondering if this will work itself out with stretching, or do I need to be more proactive in getting to an urgent care.
