This is my first time on here but thought it might give me some advice/reassurance.
My dad was diagnosed with aggressive prostate cancer in October 2016 with a Gleason score 4+5 and PSA level 16.7.
He started on a 4 week course of hormone tablets and then on hormone injections every 3 months which he is on now until December 2019. He had 4 week course of radiotherapy which finished at the end of March this year.
During his radiotherapy he didn't really suffer from any side effects. He had his post treatment follow up appointment 2 weeks ago which revealed that the hormone therapy alongside the radiotherapy has worked and his PSA has now dropped to 0.09. He has been discharged from the hospital & now has to have 6 month follow up appointments, which is brilliant news!
However, starting 2-3 weeks ago he has been extremely tired every day and feels as though he has no energy, even doing the most simple tasks making him feel weak and he has to sit down for a rest.
We were told that tiredness is one of the side effects but I didn't realise it would be to the extent it is.
How long could this fatigue last for and will it gradually improve? Is it common for the tiredness/weakness side effect to start so many weeks after completing radiotherapy?
He is also having occasional hot sweats from the hormone injections but is managing these well.
Any advice/simarities in side effects would be greatly received.
