My blood and urine results come back normal but the ache is still there, it's a ache in the lower stomach/hip it's annoying more than painful
From the information shared by you it is possible that you are suffering from gastritis. Other causes of your symptoms could be food poisoning, food intolerance, stomach flu etc. Try to take regular fresh well balanced meals. Ensure to snack on plenty of fresh fruits and vegetables and include natural yogurt in your diet schedule. This is merely an advice and not a substitute for clinical examination. Keep me posted.
Take care and regards!
