Anything under 319 (per the 2002 guidelines) is time for treatment of the patient complains of symptoms. And speaking from my experience I was getting hit over the head at that level by my wife. She said, "Mr T you are tired all the time, in a foul mood and have zero interest in having sex with Mrs T. I pity you!"
If your MD is not in tune with the 2002 guidelines either get a new doctor or give your current one a copy fast!
