                                                                                          tamarawilhite (17883)
                                                            
                          
                          
                                                          This depends on age and gender. If you are a female of childbearing age, this could be edema caused by early pregnancy. If middle-aged, it could be a sign of osteoarthritis. It could also be caused by poor circulation, a risk increased by diabetes and heart disease. If any of these cases apply to you, see a doctor.
