[|AI|]  Hello dear user! Thank you for asking us on Chat Doctor! I understand your concerns about your father and I'm trying to give some advice to help improve his health. Pain in lower extremities may occur due to nerve degeneration or compression, due to vascular diseases including veins and arteries, metabolic conditions such as diabetes, etc. To evaluate the current status of your father health I recommend go and do the right examinations such as:- Doppler angiosonography to see the arteries and veins of the lower extremities.- Blood count, sugar and lipids in the blood- Neurologist consultation if it is necessary to rule out any nerve compression which causes pain. I wish you and your father a good health! Please don't forget to give your valuable feedback and five-star rating, to help me assist you in a better way. Click at I Find This Answer Helpful too.
