<s>[INST] In the last 3 weeks since we had a heatwave, temps over 40 degrees, I have been experiencing allergy type symptoms. I am lightheaded, uncoordinated, my face and tongue feel swollen, my sight is affected, I feel sort of high and like I am ghosting or following my body. The doctor thought I might be allergic to heat, but I don t have any rashes or get itchy, my nose does not run or block, just I feel so swollen and puffy. I have had blood tests for the general body functions and all are fine. I have heamocromotosis and my blood is getting thicker and harder to extract. I am retaining fluid badly and drinking a fair bit, but not getting rid of much. I was prescribed with a short course of steroids and also Zyrtec, but this isn t really helping. It can get very scary as I feel so weird. I have tried to see if it is food related, but no real results. I am thinking it may be the air-conditioner as I am in a new residence and using the air-con for the first time. Do you have any suggestions please???? [/INST] Hi, Welcome to Chat Doctor forum.  As you describe, it appears to be the reaction of the cool air, from the air conditioner, and sometimes allergen gases may come out along with the cool air.  Or the cause may be due to the food in the new area, or water.  I advise you to consult a physician for diagnosis and treatment.  Avoid taking fruits, juices, ice water, ice cream, and the things allergic to you.  Wishing for a quick and complete recovery. Thank you. </s>
