1 month ago had elevated d-dimer in the 2000s diagnosed at ER due to chest pain (freaked me out bc I'm 34). CT scan revealed pulmonary AVM, no DVT, and was d/c'd from ER. 1 week later developed bruise inside of calf (size of fist) with pale horizontal line in middle of bruise. Bruise has faded, but the white horizontal line in the middle is now yellow colored (remnants of bruise) and is a straight line across that is lumpy. Did I develop blood clot in calf?
