My son went to the doctor this evening complaining for a while now that he had spots on the back of his throat. I had looked several times but did not see anything. Tonight was different, I noticed he had 3 black spots in a row at the back of his throat, the spots are very small. He is constantly clearing his throat, and horking. The doctor said he wasn t sure what it was and thought he should be referred to a throat specialist. I was not at the hospital with him, he took himself and then later informed me. What could this be and should I be worried? He has been complaining about his throat for a few months now.
