Hello TinaW,
Your nody will eventually absorb it, but in the mean time I can highly recommend oncology massage also known as a gentle masage to help with lymphatic drainage. Your body just needs to change the way it diverts lymphatic fluids.
Have a look in the support section on this site for an oncology massage therapist in your area. Just in case you cannot find it here is the link http://www.oncologymassagetraining.com.au/
Made the world of difference to me. The other very important thing is to continue to do any physio the breast care nurses or your surgeon may have suggested.
All the very best.
