Had a concuss 9 month ago doctor neuropsychologist says i'm fine now but occasionally my head feels hot how can i help or get rid of this it's uncomfo?

Have you considered: Acupuncture? It is sometimes quite helpful with symptom complexes that don't fit into standard western medicine diagnoses.

Check blood pressure: I will suggest to get blood pressure checked, and resume sports gradually as tolerated, if blood pressure is fine, and no other intracranial pathology, can use anti-imflammatory agents, be careful about diet too, eat less fried or processed foods.
