I am getting rashes in morning while eating breakfast for food I ate in yesterday. Last time it was dhal I ate. It starts with rashes all over the body and fainting and low BP and taking beavy breaths. I have consulted Allergy specialist, he suggested me immunotherapy but this increases the occurrence of episodes more frequently, so I stopped immunotherapy. I have gone through MRI Brain, and some tests with my interest. All normal. But Now I suspect gastric is triggering this episodes .any body understand what might be cause for this weird rashes/fainting/hyperventilation/heavybreatheNO one understand the issue clearly till now, I also do not know whom to consult (I mean specialization of doc) Thanks in advance.
