May be herpes: Herpes can initially cause itching. That's often followed by a blister that ulcerates. May cause pain, especially on urinating. The only way to tell if HSV is to do a swab of some fluid from the sore. Since you were able to see the "pimple" I'm not sure why you are asking if it easily visible. The doctor can use a magnifying glass to view it if needed. Best wishes. Always use a condom.
