Lump in Armpit 3 Weeks Post-Op Breast Implants

You may have an enlarged lymph node, but please let your surgeon examine you. No one over the Internet can diagnose you.

You should call your surgeon and let him know about it.  Then follow his advice.  Internet advice on such issues is not wise.

This could be due to inflammation caused by having surgery but you need to be examined by your PS to make sure an infection is not developing.  Good luck.

This may be a lymph node reacting to your surgery. However that is unusual.Please see your surgeon for an exam in person and do not rely on internet advice.

This lump is probably a reactive lymph node when will subside. Please show this to your plastic surgeon. 

 After breast augmentation there can be some inflammatory response and lymph node growth.   This could be meaningless and will simply go away.   It however could be an infection of some proportion and this need checked out by your doctor.   My Best,  Dr C

After breast augmentation, it is not unusual to have a reaction in the armpit lymph nodes.It sounds like the one you have is a bit larger than we might typically see. Get in to see your surgeon to make sure all is OK.
