Du Rags too tight???

  Is there a such thing as havin ur du rag on too tight?  Cause wen i first got in the wave game 4 years ago, i used to wear it on so tight like it was almost cuttin off circulation, and I got this dark spot right in the middle of my forehead from it.  I know its from the du rag cuz wen i took a break from waves bout a year and a half ago, the dark spot started goin away, and then wen i started bak up wearin the dooey, the spot got dark again and it dont go away as long as i wear my du rag.  It really messin my look up and pissin me off to have a huge dark spot in the middle of my forehead.  so is it a bad thing to wear your du rag too tight?  How tight should it be?
