I was referred here for chronic pain, expecting a thorough investigation into the root cause. After waiting two months, I was disappointed to find the doctor hadn't reviewed my file beforehand. Instead of diagnostic steps or blood work, I was simply told to return to my primary care physician. It felt like the focus was on prescribing medication rather than finding a diagnosis. A frustrating waste of time and resources.

We need more of him. He listened asked me questions I didn't feel rushed or gaslit in anyway.
