My son's royal had similar pink at one time. As KMG stated, leaving out ANY info is detrimental when looking for answers. In our case a simple change of substrate was the answer. She was too wet on cypress so I simply switched back to aspen.
Having said that, I am not sure your situation is at all the same.
I understand your love for the pet. That is really neat to an extent, however one reason I sometimes don't think royals are a great first snake, at least for some, is the fact they are VERY programmed by evolution to be solitary and secretive.
When discussing stress, you have to remember that and let your snake have plenty of space and undisturbed time. Too much love is a bad thing sometimes.
I have no doubt the issues will heal up so rest easy.
