The Injection That Worked, Then Didn’t: One Trial Worth Understanding
There’s a pattern with tennis elbow that plays out often enough to be predictable. The elbow has hurt for a few months. Gripping is the problem — a kettle, a door handle, a laptop bag. Eventually someone offers a steroid injection. It works. Within a fortnight the elbow feels transformed. Relief, and a sense that the problem is solved. Then, somewhere between two and six months later, it comes back. Often worse. And the second injection doesn’t do what the first one did.
