I am having the following symptoms: I can be extremely cool, then all of the sudden I get extremely hot from my head to my feet. I have water or sweat running off my face, down my back and legs. This will occur for approximately 5 to 10 minutes then I will be normal for awhile except for my feet which feels like they are almost frost bitten. They are cold and hurt somewhat. I wear socks and then wear heavy socks with fleece lining on top of them. This warms my feet but does not take away the cold unless I am having a hot spell. This started happening approximately 6 to 8 weeks. Ago. I have been diagnosed through my neurologist as having migraines continuously. They get to a point several times a month where I am bed ridden. I have spontaneous on my spine, fibromyalgia, and arthritis. These things are already in my medical records. I took my blood glucose today after eating and it was only 103. Do you have any ideas what could be causing this change. Also I went from being able to go right to sleep at night to being awake until 2 or 3 in the morning. Please help. Thanks.
