Just a brief bit of info that may possibly help someone else.
Diagnosed PMR/TA June 2015, up and down with various flares the last one in May of this year. However, the increase in steroids cleared head pain and some of the muscle pain, but new aches appeared - all joints - pain increased fatigue and I was in a pretty miserable condition. It did not feel like the same PMR pain on this occasion.
I saw the rhemy this week, he says it may or maynot be Rheumatoid Arthritis in addition to the pmr/ta, but doesn't want to investigate until I am off steroids. He prescribed Arcoxia 60mgs - and goodness me - what a difference. I am virtually pain free and feeling better than I have for a year - its only day two so I may be getting over excited but feel hopeful for the first time in ages.
