Were you by any chance bitten by a spider or other insect, it could be due to an allergic reaction if you were.

I would certainly see your doctor or go to the ER if this persists. They should run some blood work to rule out any blood clots and some other tests as well.

Have you seen a dermatologist, it could be erythema nodosum.
