<s>[INST] I want to know where in Vashi do we have Allergy Test (Food or Egg) facilty. My child is 10 yrs old & he is facing a recurring problem like vomitting & constant stomach pain. We have done sonography & test for Appendix, however all the results are negative. Hence one of our relative suggested Allergy test, since she also had similar problem & later it was found that she has EGG allergy. Kindly advice. [/INST] Hello I have gone through your question and understand your concern. There are various causes for recurrent abdominal pain in children which need a systematic approach. Allergy test or a USG scan is not sufficient to diagnose the big list of possible causes. As you have mentioned recurrent pain in your query, I suppose the pain is intermittent. It appears to be Abdominal migraine.No evidence of an inflammatory, anatomical, metabolic, or neoplastic process(from the sonography and blood works for appendix)that explains symptoms. Criteria fulfilled two or more times in the preceding 12 months. Must include all of the following:1.Paroxysmal episodes of intense, acute periumbilical pain lasting for one or more hours.2.Intervening periods of usual health, lasting weeks to months.3.The pain interferes with normal activities.4.The pain is associated with two or more of the following: anorexia, nausea, vomiting, headache, photophobia.Consult a Paediatrician and discuss with him the possible cause of pain to be abdominal migraine. Keep us informed at Health Care Magic of investigations prescribed and further managment. </s>
