Hello, I have quite severe wheezing for the last 2 days accompanied by metallic taste and cough. prior to this I have noticed I cough more than normal, or I start to wheeze. i was clearing out the spare room and had attributed that as the cause. I also notice my eyes water a lot and my throat and ears feel itchy. i am being treated for diabetes type 2, depression and high blood pressure. I also take antihistamines, and I have four cats. Could this be asthma?
