Hi Virginia,
Started posting June 16, so I'm new at this but not to cancer. Had 36 rad treatments Mar-May 04. Noticed fluid seeping from neck. Sounds like what you had. ENT said it was cellulitis infection, painfully drained it, kept me in hospital for 3 days and went on antobiotic augmentin for two weeks. Had to pack 3 times a day for a month. Developed it again to a lesser degree in oct 04. Augmentin cleared it up-no recurrence. Have hardness in areas of neck dissection. ENT held up therapy until Dec 04. Started stretching neck twice daily, massage twicw a day with cocoa butter and use Roxicet at bedtime. This hardness is called fibrosis due to rad. Main thing is, gotta keep exercising the neck. Also heard that a drug called pentoxyfilline (PTX) used with Vit E helps. Haven't tried and ENT never heard of it. Maybe your's has. I'd inquire. Hope this helps and God Bless you in your struggle.
Jim
