My mother aged 65, taking medications for diabetes (gemer 1), cholesterol (atorvastatin), also clopidogrel as she had 2 clots in brain on mri scanning. Her blood pressure would be 145/75 with 75 heart rate. While stepping and walking, she is having a slight pain under the middle, fourth & little toe of the left foot. Also, slight swelling above those toes compared to right foot. Kindly suggest what to be done.
