If you are having health issues, throw in all your resources into dealing with the problem. It is not the time to delay or ignore the problem. If you are in a situation where you don’t have any health problems, but you do have symptoms that could be pointing to a problem, it is time to get checked out. If your doctor says everything looks fine and there is nothing wrong with you, then ask them what they would do if they were in your position. If they say they would take action, then you need to do the same thing. If your doctor tells you that there is nothing wrong with you and doesn’t suggest any kind of testing or monitoring, then find another doctor.
