Persistent facial pressure and brain fog after a neurological episode

I am a 62-year-old man. On February 7, 2025, I had an acute neurological episode with severe pressure in my head, tingling and numbness in my face and hands, numbness of the tongue, and a brief speech disturbance. CT, CT angiography, and perfusion imaging did not show an acute stroke.
Since that episode, I have never returned to my previous condition. I have a constant, strong, bilateral squeezing sensation in my cheeks, temples, under the eyes, and across the forehead. It feels like a tight band or helmet. I want to stress that this is not a typical headache and usually not pain. It is a powerful pressure and altered sensory sensation in the face and head.
I also experience burning sensations in the neck, back of the head, and shoulders, as well as intermittent tingling or numbness in the face, tongue, and hands.
At the same time, I have persistent brain fog, difficulty concentrating and retaining information, slowed thinking, trouble finding words, and speech that sometimes becomes hesitant or fragmented. Planning and carrying out everyday tasks in the correct sequence has also become difficult. Severe chronic insomnia may be contributing, but it does not fully explain the abrupt onset after the neurological episode.
Brain MRI has shown chronic small-vessel ischemic changes, but no clear acute lesion explaining the symptoms. The cause of this combination of persistent facial pressure, sensory symptoms, and cognitive-speech difficulties remains unclear.
Has anyone experienced a very similar condition after a TIA-like or other acute neurological episode, especially constant bilateral pressure in the cheeks, under the eyes, temples, and forehead without typical headache pain? What diagnosis was eventually considered, which specialists or tests were most useful, and did any treatment reduce the pressure or cognitive symptoms?
