Possibly. It is possible that you also sustained an additional injury that was not able to be identified originally. Delayed diagnosis of traumatic injuries is not uncommon. See your doctor for further evaluation.
Possible DVT. Have your leg examined by your PCP and possibly get an Ultrasound ASAP.
