I recently started to experience internal chills most of the time, sweating in creases of arms and head. My hair is wet as if towel dried. No energy at all. I feel like I'm dying. Mood swings. No appetite and sick when I eat so weight loss. Confusion and mental disruptions in memory. I am a 60 yr old female. I have already been through menopause. Hormones? Thyroid? I have bee diabetic since 1999 and my A1C is 6.9 so I am doing good in that area. I also quit smoking and my heart hasn't felt well.
