Last night, Megan experienced an unexpected and scary medical emergency inside her home. She woke up at midnight with an incredibly sharp stomach pain and a very high fever. Because her painful symptoms became worse after an hour, her husband drove her quickly to the local hospital. They arrived at the crowded emergency room, and a nurse checked Megan's vital signs immediately. A dedicated doctor examined her body carefully to find the cause of the physical problem. After running a quick blood test, the specialist gave Megan a clear diagnosis of acute gastritis. He explained that she needed a lot of rest and wrote an official prescription for her treatment. Her husband walked to the hospital pharmacy to buy the specific pills to cure the infection. The specialist also gave Megan a strong painkiller to stop the intense stomach irritation instantly. Fortunately, the medical treatment worked perfectly, and Megan returned home feeling much better.
