What Causes A Feeling Of Cold All Over The Body Post Chemotherapy?

hi i am feeling very cold all over especially my feet. the weather has turned from very hot to cold overnight but this is not the cause. It is that deep cold feeling. When I get up each morning some days I have a lot of pain throughout my joints in my body as a side effect of medications from chemotherapy 18 months ago. this is often uric acid build up after exercise ... the next day. today took 2 665mg panadol osteo tablets to ease this pain. I have done this once before about a week ago with success. Today it is successful but i am slightly dizzy, weak and have a body temperature of 35.1 and feel cold all over.
