Hello, After An Extremely Painful Grief, I Started To Feel

Hello, after an extremely painful grief, I started to feel weak blood flow (effort on legs would triggers lack of blood in my arms, tingling, tensions in veins), mostly when horizontal in bed. It was a year ago, things got a little better but my upper body, arms still have these tensions. Also transient sensations of 'stones' or clogging, travelling through my arms (shoulder, then forearm, then tip of my fingers). Too often and too acute. Any idea?
