### input:
My boyfriend suffers from extremely cold feet and shins. Even in summer. They do not feel cold to the touch, but are very painful to him. during day he now wears double socks, leg warmers under his pants and still has to have a heater blowing warm heat on him. At night he has the same plus a heating blanket just from knees down, The rest of his body will be sweating. He has asked his MD and she says he is getting older and has not done any testing. He is on various meds for blood pressure, cholesterol, acid reflux. Always has sweaty palms.

### output:

Hello, Extreme coldness in the shin & feet are commonly due to peripheral vascular disease, diabetes, arteriosclerosis, etc. It is due to decrease in the blood circulation in the arteries or narrowing of the arteries due to fatty deposits that decrease the blood flow. You are suggested to get him clinically examined by a GP. Get all the blood workouts, Urinalysis, CT, MRI, Nerve conduction tests, etc. done at the earliest. He should also get cholesterol tests, chest x-ray, Duplex scanning, an echocardiogram, an electrocardiogram (ECG or EKG), an exercise stress test done to detect arteriosclerosis.  If diabetic, get blood glucose level controlled at every cost. Neglect may trigger the symptoms. His vitals should be normal. His treatment will depend on the pathology detected, reports of the investigations obtained & his clinical condition. In the meantime give him vitamin D, vitamin E, B6, B12 rich food or its supplements. Hope I have answered your query. Let me know if I can assist you further. Take care
