2 months post thigh lift, have developed a blood clot, so swollen can't see great saphenous vein, what can I do? (photos)

Sorry to hear about your blood clot, gene0022.
It’s good that your plastic surgeon is monitoring your situation. Just continue doing everything he says so as not to aggravate your deep vein thrombosis.
But in order to relieve your symptoms, you should walk around 5-6 times a day, if possible. When at rest, elevate your legs to promote blood circulation.
You should also ask your board-certified plastic surgeon about wearing compression stockings to prevent further complications and relieve pain and swelling.
Best of luck!
