My daughter has severe pain in abdomen, which travels upwards and makes her feel congestion in chest and throat and finally giddiness and blackout. Pain is severe and the attacks come 2-3 times a day and lasts for 30-45 minutes, mostly an hour after lunch and dinner. Doctors think it is GERD and have ruled out most other likely causes like appendicitis, gall bladder stone, pancreatitis, kidney, ovarian cyst, heart related, lung infection etc. she is aged 9 +. And is not improving even after being on Omeprazole, Debridat and Domperidone for past 4 days. Really worried whether we should wait as the docs suggest this takes 7-10 days to get well or if we should do any additional thing.
