 [ Symptoms ] whats the next step in determining cause of my 6 yr old hives how do i get dr to test for therare causes my 6 yr old granddaughter has had recurrent hives most of her life with illness or new medications recently did allergy testing found nothing did trail with amoxocillin with no hives treated hives with prednisone had another outbreak last week this time included swelling of hands and feet benadryl works mom wont take her to dr frustrated with lack of answers or treatment [ Disease ] the symptoms seems to be probably due to side effect of excess dose of iron you should take it only after a proper investigation of your haemoglobin percentage and serum ferritin levels so it is advisable to consult a physician and get a thorough evaluation done for acid reflux you can take antacids and omeprazole and simethicone for gas formation do moderate workout and take small frequent meals hope this helps
