Any condition that hampers your activity, work and life is serious. I think what you meant was LIFE THREATNING, not its not.
has triggers like loss of sleep, stress
, strong emotions like anger, hunger, change of temperature, right before menses etc. Not if untreated, every little thing will cause/aggravete it and make like and work difficult for you.
You can try homeopathy
for this condition, safely and for a permanent solution.
Meanwhile- avoid excess of alcohol, coffee, take the right amount of sleep and a balanced diet., and try to keep yourself stress free.
