Blood Urea Imbalance

My father is on medication for blood urea imbalance – due to which urea deposits in legs causing numbness and pain. At different times, he has tried Ayurvedic and allopathic medicines for this issue.
Doctors say this is caused by kidney disorders. He also has diabetes and recently suffered a jawbone fracture due to a fall – he was operated for jawbone surgery, during which they also recommended ECG due to some cardiac markers.
A lot of things. What is the order of things to be treated and care to be taken for so many things.
His jawbone wire in the teeth has been recently removed after the jawbone was repaired, a few weeks after jawbone fracture. Now he is proceeding for cardiac profile tests as per recommendation earlier.
