Hi, I'm just wondering what the actual symptoms of diabetes are, for a long time I have had trouble after I eat, I get flushed and sweaty and shaky. Within the last few months I have noticed I drink a lot! And am always thirsty, I also always have irritated itchy skin which may just be dry skin, so I moisturizer often to try to fix it. But I'm concerned all of a sudden because this last week I cant eat anything or my body just rejects it and I throw up. Could this be associated with my other problems?
