Months of physical therapy, countless massages, acupuncture, orthotics, ice packs, painkillers, an MRI and some x-rays later (and not to mention the cost), and the diagnosis about my painful right knee is really quite simple, it's Runner's Knee.
Apparently the technical term is Patellofemoral Pain Syndrome (amongst other names) and comes from overuse of the knee in sports such as running. So finally I've found a sport that I love, and that I'm good at, and I get a really common injury it seems.
Stopping running is not an option for me, so I've just had an injection in my knee to see if that can numb the pain (which is exponentially worse on hills, inclines and stairs) and I'm told it may help for a day, a week or up to four months, or not at all. Doesn't sound like an exact science does it.
I'm looking forward to hitting those streets again, so wish me luck for a pain free return to running...
