Hi, I'm An Active 30-year Old Male That Had A

Hi,

I'm an active 30-year old male that had a SLAP repair surgery about 6-7 months and about 6 weeks ago I noticed a sensitive lump in the armpit of the arm that I had the surgery on. After taking some antibiotics, the lump (lymph node) became painless and reduced a little in size but I can still feel the swollen lymph node a few weeks after treatment. Could this be due to the surgery?

Thanks!
