“Why can't I stand up straight or walk without pulling pain in my side 1 week after laparoscopic gallbladder surgery?”

Normally air trapped under the diaphragm. If this does not go away you need an ultrasound or CT scan, since it could be a hernia or adhesions trapping bowel,

It is not normal, but may be experienced by some due to pain associated with the incision or bruising of surrounding tissues. It should start to improve over the next couple weeks, but if it continues to get worse, you should call your surgeon to get checked out just in case there is a problem such as hematoma or infection.

This is not an uncommon situation. During laparoscopy, the abdomen is inflated with air. This can cause stretching of the diaphragm and can lead to a persistent irritation and pain underneath the ribs. Your surgeon may have made incisions in that general area, and those can refer pain to areas away from the incisions themselves.

Rarely, you could have a complication from surgery such as a retained stone in the bile duct or a leak from the bile duct. This would potentially be associated with nausea, vomiting, anorexia (loss of appetite), fevers, or jaundice (yellowing of the skin or eyes). If you have any of these symptoms, I would recommend contacting your surgeon directly.

Anti-inflammatories (Advil, Aleve, Motrin, Ibuprofen, Naproxen) can help with the discomfort that you are having. Other things that may help are walking and deep breathing.

Well, I am assuming you have laparoscopic incisions. This can be from the incision being close to the rib. There is no way to tell from the information you have provided, but it is not normal. The best course is to contact your surgeon and show yourself to them and get it dealt with that way.
