Adult Embryonal Rhabdomyosarcoma

Hello everyone,

I was recently (Jun 2012) diagnosed with having EMRS.  I am a 42 year old male. I had the primary tumor resected in August 2012 with the CT surgeon stating that there were "Clean Marigins" around the resected area.  I then received some chemo.  Vincristine, Dactinomyocin and Cyclophosphamide (VDC) for a while.  I just completed 43 radiation treatments.  Now, I am experiencing pain in my left shoulder (the side of the treatment).  I am a bit worried that maybe the radiation has had an adverse affect on me.  I am wondering if anyone else has had similiar issues.  Also, the Vincristine makes my hand hurt (joint pain).  I am trying to find out if this is "normal"  or if this is something that I should bring up to my oncologist.  

Could the shoulder pain be indicative of some other problems like recurrence of the cancer or a secondary cancer?  Anyone?  Thank You.
