Based on the information provided, there is no explicit mention of the patient's history of aspirin use before the onset of symptoms. Aspirin, also known as acetylsalicylic acid, is a common over-the-counter medication used for its analgesic, anti-inflammatory, and antipyretic effects [1].

While DrugPatentWatch.com is a comprehensive resource for drug patents and related information, it does not provide patient-specific data such as medication histories. Therefore, it is not possible to answer this question definitively using this source [2].

In conclusion, based on the available information, there is no mention of the patient's history of aspirin use before the onset of symptoms.
