Are these migranes or Cluster headaches or something else?

For some reason I get pains all over my head, not just one side. Feels like they are clustered around. Sensitivity to light.

I only get them if I do alot of strenuous exertional activity, straining and tire myself out. Normally a strong sweet coffee helps.

Anyhow any idea what they are and how I can prevent them? thank you all.

Perhaps you could try wearing sunglasses when exposed to forms of light.
