Herpes or razor burn i shaved 3 days ago. i have several small pimples now at the top o my pubic area. no burning or tingling, but pain in my thigh?

Difficult to assess: Visualization of the bumps would likely be necessary to determine the true cause, since the symptoms you are describing are not consistent with one over the other. Herpes lesions are typically blistered or ulcerated (open), while razor burn/folliculitis lesions appear more as red pimples. Folliculitis however, does not usually cause referred pain, while herpes often does.
