I have heard people joke that if back squats and fish oil can't fix it, you're going to die. But it is just a joke. CrossFit may be a great hedge against a lot of illnessess, but it is by no means a panacea. Sometimes, a good doctor is what you need. When it comes to acute aches and pains, if you can't fix it on your own in a few weeks, it is best to see a professional and get some help.
