If you suffer bouts of pain, your brain eventually stops listening ... but then your problem becomes chronic. The rule of thumb I have long advocated when it comes to healing (provided you are not suffering a serious issue) is to give your body 3 days for the problem to settle.
If there is no improvement on day 3, you are going to need some professional assistance: chiropractic, physiotherapy, medicine, etc. (I advocate the former first). Your body should not be so weak that at the first sign of distress of challenge everything falls apart.
Your body should be strong enough to recapture problems on its own so that they heal properly. The problem happens if you don't do anything, just hoping it will go away on its own. It will and it won't. Here's why. If you leave a pain, niggle or issue for 4-6 weeks, it will heal but the wrong way.
The result is that soft tissue changes will occur, which now means the problem is chronic and will lead potentially to other problems down the track. The other problem is that when the injury heals (incorrectly), the brain stops listening to the pain signals that are coming from the area.
Educationally, we make the faulty assumption that because we are no longer in pain that we're all fixed and everything is okay. Maybe for now, but the problem invariably comes back or evolves into something worse. Dr Tom Forest (who appears towards the beginning of the video) explains the situation in the following linked video about Upper Cervical Specific care here.
Like a child crying for attention, it takes time until your brain finally registers the true severity of the problem. One of the biggest challenges I come across the practice in North Lakes here in Brisbane is when a person comes for help with some pain or issue that "only appeared a few weeks ago."
Then when we examine their history and x-rays we uncover a problem that has been there for decades ("Oh, yeah! I had this old injury and that, but I thought that was all just a part of getting older.") Pain and discomfort are not necessary companions with getting older.
The wiser thing to do is if/when your brain registers pain that you act ... and not just to kill the pain, but to identify the source of the problem so that it does not continue to evolve to become more problematic into the future.
