Hi R.,
When my 8 year old daughter was 4 she used to complain of stomach aches all the time. There were times within a 4 month period that she would have a 10-24 hour bout of throwing up only to then have a ravenous appetite after she was done. Her ped suggested everything from stress, allergic colitis, acid reflux, a stomach bug, food allergies and we even saw a GI specialist. All tests were negative.
We are a military family and husband was deployed at the time so stress was our number one focus. I kept a food and pain journal as well trying to pinpoint a pattern for her ped and specialist to focus on.
However, I resorted to alternative medicine because the wait for the specialist was too long. We visited a Certified Nutritionist that used a computer scan, homeopathic, essential oils and supplements to help balance the body. She determined the underlying cause of the tummy aches was parasites and she was intolerant to dairy(we had eliminated all dairy at that time anyway). We used liquid supplement called Cell Food that gently detoxed her body. Within days she was pain free(I still have her pain journal today because sometimes I can't believe it myself!) The ped and the GI specialist were amazed with the results. You can read my testimonial here, mine is the 6th one. http://breathoflifeonline.com/testimonials.htm
I strongly encourage you to have her tested for parasites. Sounds disgusting, I know and it was difficult to accept that she had parasites but parasites are the number one undiagnosed caused of health issues in the world. You can read more about parasites and the symptoms they cause here. https://humaworm.com/symptoms.html
If you have questions or would like to now more about our experience feel free to email me.
Best of luck to you and I hope you can get to the underlying cause of your daughter's pain soon. I know how frustrating and stressful this can be.
Peace,
J.
