<human>: I am 46 yrs old, poor blood circulation in my right leg, my feet turn red, blue and purple, my hands have also started turning red.  I don like excessive noise, feel foggy and disorientated. Feel nausea when its almost time for a meal with headache, blurred vision at times, extremely tired could go to sleep easily, fall asleep without warning, too tired to do anything takes an effort to get moving.
<bot>: Hello, The information you have provided is somewhat insufficient to go for diagnosis. If such a patient comes to my clinic, I would ask more questions like-for how long do you have these symptoms like fatigue, headache, changes in color of your hands and feet-Do these changes occur in cold or hot environment?- Do you feel pain or tingling sensation in your hands or are they numb?- how often does headache occur, and what incite it?- have you got diabetes or any previous heart disease?- Do you smoke?- Do you often forget things? How is your memory?- have you got any tremors recently?- Do blood tests like CBC, Lots, Rats and endoscopy for blurring of vision.- Echocardiography to know the current status of your heart. Besides poor blood circulation can occur due to prolong immobility, maybe because of your job. Hope I have satisfied you to my best. I am here to answer if you still have any queries. If you do not have any clarifications, you can close the discussion and rate the answer WISH YOU BEST OF HEALTH!
