Hi Vivacious,
I also had lumpectomy 30/04/13 and 6 weeks radiation. I have a seroma, is that the same as a hematoma? Fluid build-up between lymph scar and breast scar. A big sore lump :(
I was left pretty much on my own through this, no assistance from breast care nurse, who apparently should have given me exercises or referred me to a physio. Breast Surgeon sent me to have ultrasound, but that was it. My Onco finally sent me to a lymphedema physio, (the seroma blocked the lymph system and gave me lymphedema in my truck, fluid built up all across my back, it was very painful). Hubbie was shown how to massage fluid away.
Do you have exercises? Have you seen a Physio? If not, you need to.
One thing that has been wonderful for me is the swimming pool. If all your wounds have healed, get the ok for swimming. Great exercises for the arm, and the pressure of the water on the body is great.
Search seroma's on this site as well.
Take care,
Viv
