Shoulder Pain Pump

Nice title for a post? Actually, I would describe it as a "catchy" title. I saw a website that is all about the legal compensation entitlement of an individual who would suffer from the side effects after a surgery on shoulder pain pump. Honestly, this is the first time I heard about it. And I was amazed that there were records of pain pump lawsuits in the US; AND there are also law firms that actually cater to this type of cases. Makes me wonder why there are people who would require a shoulder surgery and how come there are side effects? I am a surgeon, I would not operate on something that would jeopardize my career (straight face).
