I suffer from very severe migraines where the back of my skull (down at the base close to my neck) swells up. I would like to try some homeopathic options. Can someone tell me what would help?

It is better to use Silica 12 X  thrice a day 4 tabs each dose for one week.

Sanguinaria  30
Iris Verse     30
Cimicifuga    30

two pills each    4 days

good luck

Although it may sound silly, and you may not be into this, however if the migranes continue, try what works for me,

Wrap some Purple tissue paper aroung a bottled water and sit it on the window sill to infuse some light, after a few hours remove and stick in the fridge if needed, but not recommended and drink the water:

Purple or indigo combines the blood-warming red and the cooling antiseptic blue. It is an excellent stimulant without being an irritant. It is beneficial in the treatment of advanced stages of constipation, hydrocle, leucorrhoea, many disorders of the stomach and womb, cataract, migraine and skin disorders. It exerts a soothing effect on the eyes, ears and the nervous system.
