My sister was down on her knees mopping the floor when she got pain in her leg from the shin down to the top of her foot. She is 55 yrs old and a heavy smoker I might add. She says her leg is swollen and has purplish small bruising all over. Back of leg is tight, front is swollen.It does no help to elevate, rest, or ice it. Its been this way almost 3 days now, she called to make an appt to get in with her dr but they scheduled it a month away, Im just wondering if this could be more serious to where she should be seen right away.
