I absolutely agree with Jamie about your twisting "therapy".
I would not normally comment on any issue like this, as I have absolutely no medical knowledge, and I also think it can be dangerous to offer others "advice", as we are all so different.
However, the word "twisting" rang alarm bells for me.
I had a LTHR in 2010, in Peru, after an accident. My recovery is not 100%, but I'm not in any real pain, and if I can just carry on as well as I am now, that will be fine by me.
The only two major flare-ups I have had since then have both involved twisting. On the first occasion, it was playing Crazy Golf with a friend's son. The second time it was as simple as sitting down on a bed, laying a newspaper out beside me, and twisting round to read it.
I now avoid twisting at all costs.
All the best for your next big milestone, next week.
