My Dad has been experiencing severe, painful headaches. Other details:
1) 85 years old, diagnosed with Acute Myeloid Leukemia (AML) 4 months ago.
2) On supportive treatment for AML, which includes blood transfusions, Neupogen shots (thrice a week) to trigger WBC production, mild antibiotics & antifungal medication.
3) The headaches used to come & go, but have become a daily occurrence for the past 15 days, lasting a few hours each time up to several times a day. He would obtain temporary relief after taking Tylenol (500mg X 2 gelcaps, each time). Neurologist has diagnosed the condition as migraine and prescribed Topiramate, but today there is no relief after taking both Tylenol and Topiramate.
I wonder if there is something else that has not been diagnosed. There is no fever, nausea, vomitting or eye pain. Just severe headache on one or both sides of the forehead. Is it worth performing a CT scan (which is another difficult trip to the hospital so prefer to avoid if unnecessary)? Any suggestions on possible diagnosis and treatment options? We are desperate to alleviate the pain.
Thank you in advance.
