Yes - attn needed: There is the possibility of a post traumatic thrombo phlebitis in your leg, with resulting recent pulmonary embolus to the lungs.....A prompt visit is needed to a physician and possible hospitalization; lung scan needed to differentiate acute pulmonary embolus from any chronic lung changes from cigarette smoking. See a physician promptly.
