Based on the information provided, I don't have personal experience or a stomach condition, so I can't provide a first-hand account. However, I can give you some general information about aspirin's side effects on the stomach.

Aspirin, also known as acetylsalicylic acid, is a common over-the-counter medication used to treat pain, reduce inflammation, and lower fever. It belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs) [1]. While aspirin can have various therapeutic uses, it can also cause side effects, especially in the gastrointestinal (GI) tract.

Common GI side effects of aspirin include stomach pain, heartburn, and nausea [2]. In some cases, aspirin can cause more severe issues like stomach ulcers, bleeding, or perforations in the stomach lining [3]. These risks are generally higher in people who take high doses of aspirin or use it frequently over an extended period [3].

It's important to consult a healthcare professional or pharmacist if you have concerns about taking aspirin or experience severe stomach discomfort after consuming it. They can provide personalized advice based on your medical history and current medications [4].

In summary, aspirin can cause stomach discomfort, including pain and nausea. In rare cases, it can lead to more severe GI issues. Consult a healthcare professional if you have concerns or experience severe stomach problems after taking aspirin.
