Small hard lump in armpit

Erika888​ Medical people's reactions can be so difficult to understand sometimes. I'm sorry that you're going through the worry.

I found a jellybean-sized lump in my armpit a few weeks after lumpectomy and sentinel node biopsy. My GP felt it and thought it might be a cranky lymph node. It had reduced in size by the time I saw my surgeon and he started explaining how lymph nodes are part of a plumbing network.. he wasn't concerned.

I'd had involved sentinel nodes so I had a follow up axillary dissection. I'm pretty sure the cranky lymph node was removed based on where my scar is.  I was happily surprised when those lymph nodes were all clear.

I wonder if your elbow burn has pushed your lymphatic system a bit. I hope for you that it's something as simple as that but getting imaging done will help answer that.
