Really odd clotting symptoms, has anyone had this?

DVT diagnosed May 2025 in my right calf. Been on thinners (Xarelto) and everything was fine. Leg swelling lowered by a lot, no pain, mild weakness but I can push through it. Been about 4 months nothing crazy has happened.

I had this massive cramp while swimming last weekend in the affected calf. Now feeling twinges of very minor pain/sensitivity across the DVT area, inner thigh, and ankle. I also was stung by a bee the bottom of DVT leg foot.

I haven’t noticed any redness in the area, but I have swelling that gets worse as the day goes on. Morning it’s not swollen and midday it’s ok, at night it’s larger.

Is this PTS?
