### output:

Hi, Thanks for writing in. Chemotherapy is a stressful event and patients might have certain side effects after taking chemotherapy. It is possible that your father is still having low hemoglobin and anemia because of which there is regular headache. The doctors probably intend to say that the headache is not a direct result of chemotherapy but due to hemoglobin. Since CT scan and MRI scan have shown normal findings therefore it is unlikely to be due to any bleeding or infection in the brain. However, headache due to anemia might be occurring. Right now focus should be on increasing his nutrition and giving him a daily diet of 2200 kcal is recommended. These might be as foods which he likes and water, and fresh juices are to be given in adequate amounts. Please protect him from any infection by taking precautions. Please do not worry.
