Small BB sized lumps after reconstruction

Others likely will have more experience or info with what you are describing. I will share my experience though for what it's worth. I am 4 months out from my BMX. I had many lumps and bumps primarily on my DCIS side. After about two months or so I was getting a P.T. referral and asked the P.A. to check those areas. She believed they were scar tissue. Then I also had several L.T. session with an O.T. who is also a L.T. for persistent cording (still ongoing unfortunately- we believe scleroderma is a big part of the problem) - she smoothed most of those out. There are still harder slightly less than marble-sized area - maybe 3 or 4. I actually think these are swollen lymph nodes since I've had those on the outside of both elbows per the L.T. (cording on both sides and in my diaphragm). I am comfortable waiting until I see my oncologist in mid-March at this point. You may want to at least call one of your docs/portal message them or whatever you have at your disposal. Let them know what you are feeling/experiencing, hear their recommendation and see if you are comfortable with that. Please let us know what you find! Best with this!

Lumps are not uncommon, but do let your doctor know. If you can see them, take a picture too so you can document change.
