My mother is 87 years old and in fair health, but no history of headache or migraine problems. About six weeks ago she started having a headache every day at 1 p.M. To 2 p.M., always around that time. It was always in the left temple area. I would give her tylenol at the first sign of this (two 500 mg. Tablets, crushed and mixed into applesauce because she has difficulty swallowing large pills). Within an hour, or two hours at most, it would be gone. This happened for 11 days in a row, then stopped although the last 3 days it seemed not as strong.
One month ago she saw her primary care doctor for a general follow-up and I mentioned the headaches, and he said he had no idea what could be causing them, and offered no solution. Fortunately they had just about ended at that time.
Three days ago, she got another one, though it was earlier in the day (about 10:30 a.M.) I gave her the 1000 mg. Of tylenol and about 2 hours later the headache was mostly gone. The next day the same thing. Yesterday it came back again around the same time. It seemed much stronger yesterday. The headache started on her left temple, but later she said it had moved to an area directly below her left eye. I bought some sinus headache medicine (acetiminophen 325 mg. Plus phenylephrine 5 mg) and gave her 2 of them at 11:00 a.M. At 2 p.M. She said the headache was still just as strong and painful. I gave her 2 more of those tablets at about 2:30 p.M. By 4 p.M. She said the headache had mostly gone away.
I am just wondering what are the possible causes for this type of headache, that happens every day in the same location at about the same time. She shows no symptoms of cold or flu.
Thank you
