My teacher ( a mathematician with reputed papers to his credit) is seriously ill and bedridden in India. He is 76 years old and is suffering from Rheumatoid Arthritis. Doctors are advising knee replacement and hip replacement. He is left with no money but some compassionate people are taking care of him (I am in U.S, and my teacher is in India). He is unable to move or sit. He doesn't want to eat much. The care giving volunteers are advised by doctors to make him sit for half an hour or more which he finds very painful. He cannot sit for more than two minutes. He does not have appetite and so does not want to eat much. Ha cannot handle varieties of food and so is getting bored of eating oat meal every time. If he doesn't sit after eating, he throws up. Whenever I talk to my teacher, he is requesting me to ask them not to compel him to sit or eat. His hemoglobin is very low (4) and so doctors are advising blood transfusion. He is still active mentally and keeps up to date in Mathematics and talks to me about Math.
What can I communicate to the volunteers? Any suggestions?
Is blood transfusion, knee replacement, and hip replacement doable at this stage? How difficult is the post surgical care? There is no one to take care of him, just few volunteers.
