This patient support community is for discussions relating to undiagnosed symptoms, breathing difficulties, feeling cold, cough, diarrhea, dizziness, fainting, fever, indigestion, itching, nausea, numbness, pain (chronic), paralysis, rash, sweating, swelling, urination problems, and vomiting.
You should drink plenty of water and consult your doctor for a clinical examination and get a urine examination done.
This would be able to help with the confirmed diagnosis - whether this is urinary tract infection or appendicitis.
You would need a course of antibiotics if it is UTI.
Let us know if you need any further information and post us about how you are doing.
