Hi I'm An 80 Year Old Male And Have Been

Hi I'm an 80 year old male and have been experiencing periods of mild shaking cold and the hot during the evening. I was anemic and was put on 10mg/ml testosterone cypionate injections every 10 days; however, my nephrologist asked me to reduce it to bring my hemoglobin down to 11 or 12 because he was concerned about increased stroke risk - I dropped to 0.4 ml every ten days for several months. Then my PSA had a sudden rise from long term 1.0 to a 2.1, so in taking with my urologist we decided I should try stopping the testosterone completely. I will be retested in early September, but suspect I am back to being anemic. Could this possibly cause the alternating hot and chills?
