This scares me just reading it - my coworker got a DVT after a 13-hour flight from Seoul. Same thing: swollen red calf, burning pain, couldn’t walk normally. Doctor put her on blood thinners (rivaroxaban) right away for at least 3 months, told her to keep moving gently, elevate the leg, and wear compression stockings during the day. She said the pain eased in a few weeks but full recovery took a couple months. This page broke down the treatment steps clearly: blood clots in leg symptoms and warning signs covers meds, what to expect, and warning signs. Don’t skip follow-ups; blood thinners are serious but super important.
