Fatigue after Eligard and proton Beam

In November 2020 I had a six month Eligard shot, then completed 44 proton beam treatments on April 9, 2021. Today August 2, I have cases of debilitating fatigue at times and continued hot flashes that seem to be more frequent and more intense. Also need to take Uroxatrol to make urination easier. In May my PSA was undetectable, testosterone 17mg/l way below the 175 mg/l that is the low of the range. Has anyone else had these symptoms?
