Hidden pain in the stomach after a cold is over may be related to gastrointestinal dysfunction, gastroenteritis, pelvic inflammatory disease and other causes. 1. Gastrointestinal dysfunction: the use of medication during a cold may lead to imbalance of gastrointestinal flora, resulting in dysfunction, abdominal pain, bloating and other symptoms. 2. Gastroenteritis: As bacteria and other pathogens invade the gastrointestinal tract, they can cause inflammatory reactions and symptoms such as abdominal pain and diarrhea. 3. Pelvic inflammatory disease: Inflammation of the uterus, fallopian tubes and other reproductive organs or surrounding organs due to infection by bacteria and other pathogens can cause vague pain in the stomach. It is recommended to go to the hospital in time to clarify the cause of the cold, and to carry out standardized treatment under the guidance of the doctor.
