Hi. I Have Finshed Chemotherapy And Radiotherapy For Breast Cancer

hi. I have finshed chemotherapy and radiotherapy for breast cancer but have been on steroids for a year however i was weaning off them down to a dose of 2.5 a day gradually however my breathing got very bad and i was put back up to 30 2 days ago reducing to 25 today im also on inhalers and an antibiotic.
this happened to me before whilst on chemo and i had a blood transfusion and hospitalised, can you tell me if a drop in body temperature is somthing i should be worrying about as im vry chilly . i have a letter to go to the hospital if my breathing worsened which i dont think it has but im freezing, should i be concerned,?
