Why frontal lobe/prefrontal cortex area of brain has minor constant pain during emotion triggers/stress? is this a kind of neuro/brain inflammation caused by emotion traumas/stress for many years? & how to heal permanently, recommended medications?

Based on your brief description, would believe you are having tension headaches triggered by emotional upset. Another possible trigger is dehydration. You can see a neurologist if you desire, but a better focus would be to learn stress management from counseling if available. We could help you start via a virtual consult here at HT (www.connect@healthtap.com).
