I understand your concern. If multiple tests have come back negative for herpes, it's encouraging news. However, if you're experiencing persistent symptoms that are not improving and resemble a rash but don't align with typical causes, it may be helpful to consult with a dermatologist or another healthcare provider for further evaluation.

A dermatologist can offer expertise in diagnosing skin conditions and provide guidance on potential causes of the rash beyond infections like herpes. They may recommend additional diagnostic tests or treatments tailored to address this specific issue.

It's essential to seek professional medical advice from specialists who can assess your individual case comprehensively and offer personalized recommendations based on their examination findings.
