<s>[INST] Hi, My mom is about age 45. Since one month she is suffering from one problem. At the right leg(above ancle) there is black mark of size 50cm*50cm . Everytime she is getting itching problem at that place and some doctor s are saying that will stops our blood circulation to the right leg. Could you please suggest me some useful medicine or homely prepared items to remove the black mark. [/INST] Hi there... Your doctor might be right. It could be caused by poor blood circulation, or she might be having a condition known as varicose veins. Avoid prolonged standing/ sitting, which causes venous stasis and poor circulation. While sleeping, keep the foot end elevated on 1 or 2 pillows. If she is overweight, she needs to lose weight gradually. After consulting a doctor, she might need to use compression stockings on the legs. Hope this information was helpful to you. </s>
