My 8 year old son was at a pool party and started complaining about pain in his stomach. Well, it never stopped and became very severe throughout the night. With no sleep between the two of us, the next day we saw his peditrician who thought it was acid reflux - since the pain in his abdomine was his only symptom. They put him on Maalox & Previcid. The pain which was described as "stabbing" pains worked like contractions: high peaks, low peaks, sometimes disappear for hours and then came back stronger for six to twelve hours at a time. He stayed in hospitals a total of seven days in a two week timeframe. Throughout this whole time, he had CAT scan, x-rays, ultrasounds, celiac, h-polyeri, merkels radiation procedure done, urine, blood, stool to check for parasites/bacteral , allergy testing-- all came up negative. I am so afraid it is going to come back. The pain for my son was unbearable - he is still getting back to himself. One thing, within that two week period, the pain moved from center abdomine to lower left side. The Pedatric Gastroentologist had no answers for us and could not diagose. Any ideas?
