Thanks for your concern, Blurto, I appreciate it! I certainly won't do anything hurtful, and haven't pushed it since my initial period post-surgery of feeling great.

Was your initial surgery a rib-resection? I couldn't tell from a post on another thread if you just had a scalenectomy and/or tumor excision. Like I said, I don't think there's much you can do to suppress scar tissue from forming, short of using barrier film, which has its limitations. I intend to have full use of my arm after a year or so of recovery, which is why I opted for surgery in the first place, and I suppose there will always be the possibility of needing further surgery. I'd like to avoid that, of course, but I can't suppress scar tissue.
