My friend at work complained of an aching stomach, vomitting and diahorrea last september. She was diagnosed with gastroenteritis.
In February she was still sick. After visiting several doctors with the "gastro" diagnoses, she finally found a doctor who thought it might be worse...... She was diagnosed with Bowel cancer, stage 2.
Five months after the symptoms started she finally had the right doctor and the right answer. Had they realised earlier, she would not have needed Chemo, and she could have just had radiotherapy.
She seems reasonably well just now and is coming back to work next week so I will be thrilled to see her, but I really do encourage you all to trust your gut instinct. She knew something was wrong. And don't be afraid to ask for second opinions.
A stomach ache may not be just a stomach ache.
