I am having chemo for breast cancer and I am experiencing a really cold head. If I take the temperature of my forehead it's 36.5 but if I take the temperature of the top of my head it's come up 33 or doesn't read, just says low. I have a headache all the time and the pain feels like brain freeze, like when eating ice-cream . I have had blood tests and infection has been ruled out . I am walking around with two hats on , even when i put a hot water bottle on my head it doesnt help. The only way I can sleep is with my head right under the duvet . This has been since my last round ( round 2 ,day 8 ) , at first I put it down to the cold cap , ( which isn't working) but it's still no better 8 days on. Any ideas because all I get told is they have never come across this before.
