Thanks for info from LynEyre and Colwichchris.
This thread is as related to my issue as any other -- except that my issue did NOT follow surgery. Mine arose out of the blue, first time in my life. Having said that I am also age 82 for the first time in my life and thus reasonable that there will be a first time for everything.
I hesitate to use the word "PAIN", preferring as description "persisting ache" or "soreness". Five weeks after this first arose I still do not have definitive proof whether this is muscle/tendon related or the result of metatstaic cancer tissue spreading and squeesing on bones and nerves and vertebra foramen (specifically impacting my right thigh but not lower leg, while left thigh remains 100%.
If this is due to muscle tighness or knot in vastus lateralis or medialis or sartorius (not hamstring), or lymph node, a really knowledgeable masseur or masseuse hopefully can rectify this condition. I paid two sessions of £70 and £55 for massage, but the practitioner obviously did not have the insight for pinpoint-precise remedy. In two days I shall see the Oncology Registrar in my prestigious London hospital, hopefully to get a diagnosis and remedy, hopeful not confident.
My prostate high PSA alarm was known 11 years ago. Androgen deprivation following confirmation of metatasis was started by my consent only two years ago, comprising daily bicalutamide and 3-monthly Protap injection. For 11 years I was totally asymptomatic from anywhere in my body and persisted so -- until 5 weeks ago. Up until 5 weeks ago i did a scenic exercise walk of 1.5 miles per day taking 50 minutes and feeling noticeably better for it.
I shall discuss with the Registrar whether to start Enzolutamide or Arbiraterone.
Docetaxel I am wary of as it has a high chance of triggering total hair loss. Info and experience would be appreciated.
