While I was being diagnosed I got a very intense pain in my hip that I was convinced meant I had advanced Prostate Cancer.
They said I hadn't but I was never convinced. The pain did very slowly subside. After my op I went to the GP who prescribed ibuprofin cream, which did no good, and a psa test to rule out PCa spread. He said it's most likely arthritis. It's still a bit sore but I think it is arthritis now.
I also got a bad back pain, same thing.
During diagnosis I was told not to blame everything on PCa but it's hard not to think about it.
