[An update as to the latest issue.]
The progress has continued, though the swimming has slowed with a return of cooler weather.
I've gotten strength in parts of my shoulders which never had them before. This, in turn, allows them to move to new extremes and several releases have been quite promising. I, too, can perform a controlled back arch that I couldn't have imagined only weeks ago.
Yet, a problem has finally surfaced which I have long feared, and hinted at before.
I have long noted that my two sides seem to reflect issues. The right shoulder needs to develop one way, the left the other.
Most often, however, when I try to stretch, or make adjustments, I use both arms the same way.
More often than not, I assume, this has been harmless, as the adjustment occurs on one side, where the other side maintains the status quo. It may have been a longer process because of this, but progress was still happening.
Now, I am not so sure.
My left thumb, quite easily, becomes a lightning rod of pain. It's like the tendon going along the side of the thumb to the left wrist is pulled too tight, from the shoulder, and any pressure on the thumb brings intense, rather sharp pain.
I can do an adjustment to the left shoulder (I can't quite explain it - it's like pulling the arm up the shoulder, which sends slack to multiple other places), and the pain instantaneously goes away.
However, I have as yet been unable to identify what I am doing that returns the left arm to this painful position. I only know I do it as soon as I let my guard down, and I do not maintain attention anywhere near as well as I did 7 years ago. It's been happening 10-15 times each of the past 4-5 days.
Don't get me wrong. The pain level has gone up, but it is not as mentally taxing as when I feel like a knot exists that I cannot figure out how to undo. I am not at wit's end over it.
At least not yet [knocks on the desk].
There is a part of me that envisions this puzzle as one of the last. Should I figure out how to properly rehab both arms at the same time (a maneuver that will no doubt feel awkward as all hell at first), I will find myself on a path much more directed towards where I want to be.
One can hope, anyways.
