Welcome to OCF. We will help you with your father. Im so sorry he is in bad shape. Treatments are brutal and recovery can take months.

You dont mention where his tumor was located. Are you in the US? Every country differs in their medical system and ways to treat patients.

As an OC patient Im surprised your father is able to swallow pills. Pain killers can be very large and difficult to swallow. I would suggest making an appointment with the doctor and letting them know he is in so much discomfort. There are many kinds of pain medications to help him, some are liquid and some are a patch which gets changed every 3 days.

His intake is the key to his recovery. Every single day he needs to take in a minimum of 2500 calories and 48 oz of water, more is even better. He will feel horrible if his nutrition isnt even close to the above numbers. This is necessary to rebuild his body after what he has been thru.

Many OC patients will talk with therapists and take anxiety meds. Your father has been thru alot and its not easy to get past this mentally. I would suggest seeking out someone at the treatment center for him to talk to.

Best wishes with everything!
