My hematoma was still quite swollen and painful when I had the lumpectomy but the surgeon and plastic surgeon (I had a reduction also) felt it was safe to go ahead with the surgery. I think it was about it 3 weeks after the biopsy. I used ice packs and that helped a lot.
Hope you get relief soon.

Hematomas are interesting> After my final surgery in Dec of 2022, I noticed the bubbling at the stitching on my left breast. Day 2 it was more. I took a picture and sent it to my doctor trough the portal. On the 7th day which was my day post op to visit my surgeon and plastics doctor., it had gotten bigger. I must add the skin bruising was crazy blue so all of it was not so pretty. By this time, the hematoma had grown. They had the pictures. My breast surgeon was 1st in the morning and looked and asked questions, she got on the phone and called the plastics dr. I doodled about after she assured me the next dr would take care of me.
I could not figure out what to eat, drank some fluid, had a few chips and got a call from the plastics dr to come earlier. Whoa.I got there and was told my plastics dr was on a plane, but he set up another dr to do the surgery!!!!! At 6:00pm, because i did not have lunch or eat i was cleared for surgery. The dr had to open me up, cleanout that breast and ensure no infection had set in.
After I had more drain tubes, but these were bigger and sturdier then the first ones i had. Easier for me to drain without feeling like i was pulling them out. The dressing where the tube enters the skin did not need changing like the other one did.
All in all, I say if you have pain or something is not right, notify the medical team. I found out later my breast surgeon followed up on the plastics dr to make sure i had the surgery the same day. Not everyone has access to this type of care. That is not right.
