Hi, Welcome to Health care magic forum.
As you describe, you had the
concussion and the related head ache,for some time, after its cure also, you had the psychological followup head ache, it may not have any evidences left.
When ever you have any tension in the mind, you may get head ache.
I usually prescribe to my patient with such symptoms alprazolam.5mg,
ranitidine, and
paracetamol when ever there is head ache.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods.
wishing for a quick and complete recovery. Thank you.
