Light colored, loose and chunky stools along with lower right side rib cage pain after gallbladder surgery 2 weeks ago. normal?

Yes: Your stools may take time to adjust to a new normal after gallbladder surgery, as you no longer have the bile salts being secreted into the intestine to assist with digestion. As for the R-sided rib pain in the area of the surgery, it is not uncommon to have some residual soreness from the procedure itself. If redness, fever, distention in setting of the soreness would prompt more urgent check-up.

So far so good...: Your state 2 weeks after gallbladder surgery seems as good as it can be. At this time, it would be reasonable to give time & patience for further self-healing as long as slowly but surely getting better in pain & general well-being. Of course, still keep in touch with your surgeon for follow-up or urgent care as needed if the clinical course reverses undesirably. All the best to health....
