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????
