Hello, I am a diabetic and was told by a doctor about 5 years ago . I know very little about it ...all I do is eat and take my meds. I check my blood sugar and sometimes it’s up to the 300’s but I feel fine but for the last few days I have been feeling really bad , cold sweats any time of day and at night I completely soak the bed and have to dry off and change my clothes two - four times a night. I have a rash on my lower legs and it seems like I have some kind of like poison ivy on the rest of my body. My lower legs are also very swollen. I don’t know if this is related but can you please tell me what diabetic ketoacidosis ? Thank you very much John
