Just curious to know if anyone else who has had a radical neck dissection experienced major shoulder soreness/pain...

I had my neck dissection almost two weeks ago, and my shoulder and right under my collar bone sometimes feels awful, especially if I stand/walk for awhile or sit in certain chairs. I guess my shoulder is feeling the pinch of not having one of the major muscles there anymore...

The docs said he wanted me to heal up another few weeks before recommending physical therapy to strengthen the other muscles around the one that was lost. Any other tricks to keep the pain down or work out some of the soreness? I feel like Randy Johnson after throwing 135 pitches... OK, not really, but it does hurt...
