hi jeanne,
i feel your pain, or should i say i felt your pain, the joy or not being able to lift your arm higher than your stomach
when you say breakfalls are you talking about 'rolls', or 'flips, i hads a friend who has just recently started to learn hoe to 'flip' out of techniques and he found that by going back to looking at how he rolled he found that he had a problem on the same side, when he fixed that he started 'flip' withoput any trouble, so if its your 'flips' i would suggest looking at your rolls.
hope it helps
steve
