I have a DVT near my left Subclavian artery. What risks do I run when I work my arm to hard and it swells? - dvt more condition_treatment

I had my DVT for about a month. I'm on warfarin and my INR is 2.7 or less. My arm is swollen, even though they used. What kind of risks that I take my stand, if my arm is swollen?
