Why do I have a wavelike sensation in my head after a stroke?

[Pa101]

I am 72. I had a mild hemorrhagic stroke in 2014. MRI revealed abnormal cerebral artery with Moyamoya-like vessels. ( Moyamoya disease has been ruled out) I suffered no effects from the stroke. For the first year, I felt slight burning sensations and quirks on the affected side in my head. These are gone and for the last 5 mo. I feel waves or flow on the affected side over my eye and across my head where this abnormality is. I have no pain. This continuous flow feeling is disturbing.
