Yes! I've been fighting my problem since before Christmas. I went to the PT and she gave me some exercises to do and I'm to use ice frequently. It's slowly getting better but when I cut it starts hurting again. Ice your shoulder after you cut, that may help the inflamation.
Try getting a new blade for the rotary cutter-a good one. Change the table level, maybe do you cutting on a slightly lower table....or better yet, tell all your quilting friends you're having problems and one may come over and cut for you. I belong to a charity quilting group and when I said I couldn't cut because it hurt, the next time I had several people give me bags of squares and strips.
Good luck,
