Is it normal? does it mean I have Pure O? Its the only symptom of Pure O that I have.... BTW, these thoughts bother me, but not to the point where I have anxiety attacks.
Hello.  The thoughts are intrusive and persistent. This not a normal occurrence unless you are not bothered by them, and they are part of a thinking process that is productive and goal oriented. If intrusive thoughts are the only symptom, without an obvious or overt compulsion, you can consider the possibility of Pure-O, which is not an uncommon condition. For a diagnosis, you will have to get a thorough evaluation done by a mental health professional.  Regards Abhijeet Deshmukh, MD
