Hi friend
Dont worry about ur problem,headache is not due to
hair transplantation. Already you have consulted
neurologist, everything is normal. you should be
consult a psychiatrist and he will be help you how to over come your problem, teach you some
relaxation techniques. Avoid artificial drinks, some tyramine contain foods like cheese,stored pickles,ice creams, chocolates. Eat fresh vegtables, regular exercise, brisk walk, help u to solve ur problem.You have not given details about ur age, any family history of
hypertension,diabetes, any substance use(alcohol, smoking).
If it is migraine mostly unilateral, it can treated by sumatryptan, analgesics and newer drugs. avoid stressful activities, maintain sleep shedule, sleep hygeine.
avoid excess salt, fat diet.
all the best
