Based on the symptoms described, it is recommended that your partner consult a healthcare professional. The location and intensity of the pain, along with the swelling in the abdomen, are concerning and may indicate a possible intestinal issue. While over-the-counter medications may not be suitable in this case, staying hydrated with oral rehydration solutions from the pharmacy is important. Applying a warm compress to the painful area may help ease discomfort from intestinal spasms. If these measures do not provide relief, it is best to seek medical advice.
