If the pain in the stomach is caused by colitis, it is recommended that the patient go to the hospital for relevant examination, and when the diagnosis of colitis is clear, then under the guidance of the doctor, appropriate oral painkillers can be given to relieve pain, and after the pain is relieved by the painkillers, it is recommended that intravenous ceftriaxone sodium or penicillin injection be given in a timely manner for anti-infection treatment. Only after the inflammation in the colon is controlled, the symptoms will be effectively relieved. It is recommended to take ibuprofen suspension or ibuprofen capsules for pain relief, and at the same time you can take antibiotics, such as amoxicillin capsules or cefradine capsules, etc. However, if the patient chooses infusion for treatment, oral antibiotics are not allowed to avoid repeated use of drugs, and only when the infusion is stopped for anti-infection can you choose oral antibiotics for anti-infection treatment.
