In the days following a seven hour long car journey, so sat in one position for hours, I developed a small lump in my calf. My calf muscle also feel tight and swollen inside my leg. I’m a bit concerned it could be an a blood clot. Eight years ago I had the same symptoms after being on crutches for months and ignored it. The next night in ended up in A and E with a pulmonary embolism after ignoring the blood clot symptoms. Would you seek medical attention in my situation. I don’t want to waste a gp appointment but it’s not getting any better.
