I Am 2 Wks Post Op Gallbladder Removal. My Gallbladder

I am 2 wks post op gallbladder removal. My gallbladder was full of infection but no gallstones. Last year my GI doctor did an endoscopy and found a cyst in my pancreas and liver. I have been considered prediabetic for two years. I have also been having bad headaches eventually sending me to hospital. Can these head aches be associated with my gallbladder issues or maybe the cysts found last year. I plan to have blood work done soon and requesting bilirubin levels for my liver.
