If you’re thinking about getting an injection for knee, hip, shoulder, or tendon pain, this is me cutting through the marketing and giving you the surgeon-level reality check. In this video I break down the big buckets people get offered—cortisone (steroid), hyaluronic acid (HA), PRP, and the whole “regen/stem cell” universe—and I explain what these injections actually do (and what they absolutely do not do). The goal isn’t to dunk on injections; it’s to stop you from paying for hype or getting a needle when the real problem is missing rehab, wrong diagnosis, or bad expectations. I compare PRP vs steroids vs HA in plain language: what tends to help pain, what tends to be temporary, and what’s often overpromised as “regeneration.” Then I go into the part nobody advertises—risks and complications, including how technique, sterility, and accuracy matter a lot more than people think. I also call out common injection misuse: using shots as a substitute for strengthening, loading, and fixing the mechanics that caused the problem in the first place. Finally, I give you a practical checklist: when an injection makes sense, which joint/tissue scenarios it fits best, and what questions to ask about guidance (like ultrasound/fluoro), credentials, and safety. Think like a surgeon before anyone sticks a needle in you.
