Hello. I am a Male 32. I had my gall bladder removed 4 days ago. Since I have had strange pains and feelings. Nausea after I eat Everytime. I realized after it's removal my stomach will have swelling, but it feels like there is a Large Knot just right of my Belly button. I also have had severe Hunger type pains. It's the only thing that I can compare it too. Very bad and painful pains that resemble Severe Hunger pains. I have also had headaches since the surgery. Mainly the right back of my head, it feels like there is a Knot under my skull almost. It doesn't hurt severely, but it does hurt sometimes worse than others. And nothing seems to help. Almost a throbbing pain. And of course pain across my entire abdomen. Top to bottom. Side to side. Which is to be expected I guess. But I have have more pain in my right chest and under my left breast off and on. What of these are to be expected and not?
