I am having the same issue. That's how I stumbled across this thread. Attempting to find a correlation and some answers. I am almost 2 months out, post gallbladder removal, and have had severe migraines lasting 3+ days almost weekly. It is taking a toll on me. I'm having more bad days than good lately. I did read somewhere that it has been linked to the bile leakage into the system post gallbladder removal. That's the closest I have found to any answers regarding the matter. I have suffered from migraines since I was a kid. However, since being grown, have only suffered from them once every 3-6months. Until having my gallbladder removed. As I said, it's now been on a weekly basis with more days of having them than not. I hope that as time goes on it will subside and lesson. I have an appointment on Wednesday with my family doctor and will Definetly be speaking to her in regards to it and see what she thinks or says. I believe there is Definetly a strong relation to having gallbladder removal. There has been nothing else that correlates to this change in frequency, severity & prolonged period of having them. It is definitely frustrating and taxing on my body as well as mentally and emotionally. If I receive a definitive answer on Wednesday when I see my doctor, I will definetly reply/comment again and let you & others on this thread know if there is in fact a direct relation to gallbladder removal.
