heavy feeling on side of diagnoses

I'll second that, Idaho -- truncal lymphedema. There's treatment, non-invasive and no drugs, but skilled gentle lymph massage and usually some kind of compression (most of us use regular camis or shapers).

Here's information on truncal lymphedema:

And here's a page about finding a well-qualified lymphedema therapist near you:
http://www.stepup-speakout.org/Finding_a_Qualified_Lymphedema_Therapist.htm

Lots of doctors don't know much about truncal lymphedema. The medical professionals who do are the well-trained lymphedema therapists. You need a referral from any doctor on your team. Call before you go and talk to her/him about their experience with truncal lymphedema.

Sure hope you get answers soon!
Be well,

Faith-keeper, the StepUp-SpeakOut.org site has lots of information on all aspects of post breast cancer lymphedema. If you have questions you can't find answers to, there's a Lymphedema After Surgery board right here at bc.org. It's further up on the board index page. Please feel free to hop on over there and ask anything -- lots of helpful "swell" ladies over there.

Gentle hugs,
Binney
