So I just got back from a 2 hour flight and a 4 hour car journey and I just got into bed and my legs hurt. They ache and it kinda feel like a burn and tingly feeling and both my legs are kinda warm to touch. I'm panicking it's a blood clot. I fly once a year. My legs don't look swollen. I'm only 20 but I'm still scared it's a blood clot and I'll die. Could it just be aching muscles from the travelling?
