I had my second Feldenkrais session yesterday. For the good news, a lot of the changes from last week stuck. My right side is now supporting force almost as much as my left. For the bad news, my right side is weaker from protecting it over the years. The teacher did a number of strength tests, and my right hamstring and hip were significantly weaker.
I was given a simple prescription of squats, single-leg squats, and side step-ups to equal out the strength levels on each side. I like this because it is a natural, simple solution to the problem.
In terms of bodywork, what I thought was a knot in my upper back actually turned out to be a tilted vertebrae. This issue was worked out during the session. The tightness that was there in my upper back is now completely gone. I have no idea how long it was there, but it feels like my upper back is perfectly healthy now.
I still have some lower back pain and stiffness. Hopefully, this will get worked out in the next session.
