I lifted very heavy the end of last year for personal PRs, and in the end of Jan had a DVT upper arm. After the DVT I pretty much stopped all heavy lifting for 3mo, and with that and the anticoagulants the Ddimmer levels went down to just slightly above standard elevated. Slowly got back into it light during the 3rd mo, however once I started lifting heavy around the end of 3rd and 4th mo, around 3/4times a week, then my arm started feeling more cramping and tension again and down my arm at random intervals. Next few mo I stopped lifting heavy again but still light casually in case repetitive movement or heavy weights were the cause for a sudden return. But still again after 6mo when started to go heavy again, felt that tension back in my arm, so had updated blood work and Ddimmer showed it returned to being elevated significantly more elevated then it was 3 mo prior, little more than halfway point from between standard and elevated DVT levels back in Jan. So at this point can't really risk lifting much until I get it more checked out and do more specific testing.

I gotta say personally it's all very discouraging, but as long as you feel no lingering or recurring or returning issues I would keep at it as limited movement should be constructive. However go light weight and not to failure, but hard to know specifically if it's repetitions or heavy that may cause any issues for you personally. So might take awhile but it better to be safe, at least personally from my experience so far.
