Getting relief from head aches is a good sign. It may mean your brain is getting better at regulating intracranial blood pressure. Reducing your brains need to regulate pressure allows it to heal and get better at regulating pressure.

There are plenty of people who rarely have head aches yet deal with cognitive and memory issues on a daily basis. I went years without chronic head aches until 18 months ago when I banged my head. Now, they are almost a daily occurrence.

Count this as a single improvement. Continue to moderate stress. In a month or so, you may try to increase your work-out load. If the head aches return, reduce your work-outs by 10% lower pulse or a similar effort metric than the pulse that causes the head aches to return. Then, slowly increase workout effort but stay under your head ache threshold.

And, enjoy being head ache free.

My best to you.
