Having taken Abiraterone for two weeks now I can report that I feel better generally but I still have some discomfort in my groin ... so I bought myself some walking poles to make walking easier.
They were just £15, hardly top of the range, but they should take some pressure off my hips and pelvis etc.
In the event, just this afternoon, I walked for just 45 minutes, quite slowly from Alport up to the packhorse bridge near Youlgreave ...

I'm not a big fan of walking poles but at least they enabled me to get out into the countryside. This may be as good as it gets unless my pelvis improves ... somehow.
We'll see.
The other news is that the Abiraterone hasn't affected my kidneys or potassium levels etc. The pharmacist declared yesterday that the results of Tuesday's bloodtest were "absolutely fine".
Finally my compact digital camera has gone kaput so I'm going to have to replace it or stick with my SLR which is bigger and more cumbersome. The two photos above were taken with my phone !
It will be interesting to see how my groin/pelvis feels during the night and in the morning. It is surprising how you don't realise as you turn over in bed how your body 'corkscrews' on your pelvis ... until you have a problem with your pelvis. Ouch.
