It also made sleeping difficult, as for some reason lying down was extremely uncomfortable. I ended up sleeping in a chair for several months.
I ended up cancelling a conference visit and talks just because I felt so awful and I wasn't even sure I could sleep in a hotel away from home.
One thing I look back on and realize now is that it really changed my behavior. My temper was shorter and my judgement about how to interact with others was much poorer.
Fortunately, it eventually resolved itself. I used to have flareups for a week or two every few months, then for a few days less often, and now it's been a few years since I've felt it.
All of which is to say I feel for the author. This sort of thing sucks. For anyone else who's experienced any sort of similar pain, I would encourage you to continue looking for solutions. If you can, enlist family or friends to help you do so.
I think that after a while you forget what it feels to be pain free, and it becomes easier to accept your current state. But once my pain resolved itself I realized how much of a difference it made in my life.
