Glad to hear ur gallbladder doesn't need to be removed. Great news!!!! Maybe you can take an herbal that will aid it so it can get better. U know I never thought itchy scalp was due to the Mirena bc I have dreadlocks so I always contributed 2 my hair being dirty but even when I washed my hair I thought to myself wow my hair is itchy. But bc I didnt always use the same shampoo or conditioner I thought perhaps I was allergic to the shampoo or conditioner but now u mentioned itchy scalp I noticed My scalp is always itchy. I mean really itchy to the point I will scratch until my scalp will bleed. Will definitely google itchy scalp to see if its linked to a weak organ or the Mirena.
