The story of actor Andy Whitfield is a disturbing and educational example of a case that met these conditions — for sure the first two, and probably the third as well if we knew the details. Whitfield was the star of the hit TV show Spartacus (which is worthwhile, but rated very, very R17). The first sign of the cancer that killed him in 2011 was steadily worsening back pain. It’s always hard to diagnose a cancer that starts this way, but Whitfield was in the middle of intense physical training to look the part of history’s most famous gladiator. Back pain didn’t seem unusual at first, and some other symptoms may have been obscured. Weight loss could have even seemed like a training victory at first! It was many long months before he was diagnosed — not until the back pain was severe and constant. A scan finally revealed a large tumour pressing against his spine.
Grade III (severe): A complete tear in your muscle that causes severe pain and swelling and you can't bear weight on that leg, making it difficult to walk. You've also lost more than 50 percent of your muscle function. These injuries are less common and may need surgery to repair the torn muscle. They can take several months or more to completely heal.
