About 3 weeks ago, when I got up, in the night, to use the restroom, it felt like my knee was messed up, I had gotten a really bad sunburn, so I associated it with that. But now the lower part of my right leg, mainly around the ankle is super red. Also, I could feel knots in my calf. Now it seems to have went lower, my ankle is really stiff and my foot feels like I am walking on broken glass. I am wondering if it is blood clots? From what I have read, read 3 different cases and they all sound like my condition, and it is blood clots. Any info would be greatly appreciated!
