2 and a half weeks ago I got a bad bruise on my thigh that was almost the size of my palm. It swell and hurt really bad. But now it doesn’t hurt and the bruise looks gone. Like there’s a yellow patch left. My concern is, next to the patch there’s this purple blood? looking thing under my skin. It doesn’t hurt. Neither the yellow patch or the purplish one hurt. Theres a lump on the yellow patch and in the purple one the color is in squiggly lines? My question is, what is that lump on my bruise, what does the purple squiggles mean, and will it go away?
