Has anyone experienced a link between migraines and gall bladder disease (in women)?

I am 28 years old and have suffered from migraines for half of my life so far. I've been to numerous neurologists. The first one fired himself, saying he's tried everything he knows. The second one insulted me and had no interest in treating me and the third is " stumped", referred me to a colleague who does Botox injections (who I am scheduled to see tomorrow).

I have also been having gall bladder attacks where I have mild to severe pain in my right abdomen, sometimes radiating to my back. The pain severity depends on what I ate. I had a hysterectomy a year ago and my gyn, who I never mentioned this pain to, said my gall bladder looked large when he was performing my surgery. I thought the pain was probably ovulation and shrugged it off until then.

There seems to be a link through personal experiences I have read on medical blogs but doctors insist there isn't one.

Before I subject myself to needles in my brain, I'd like to get real life experiences and opinions. Is there a possibility that removing my gall bladder, IF it is need of being removed, could stop my migraines?
