Clear mammogram, swelling under left armpit lymph nodes. worse after 2nd pfizer.no fever. cystitis symptoms. can bladder infection (urinary) cause left armpit nodes swelling?

Hmm. Can’t think of many ways this would happen. Tuberculosis maybe. Of the lymph node, bladder, kidney but very rare in US. Or lymphoma. Or arm injury and cystitis. Discuss with your team again.

Lymph Nodes are localized glands which grow large temporarily to accommodate more infection fighting cells and filter out debris and broken cells from the lymph due to an infection. It has been recognized that the Covid-19 vaccines can cause armpit lymph node swelling. The swelling lasts 1-3 weeks then recedes. Most Dr's are suggesting that mammograms be delayed up to 8 weeks after 2nd vaccine.
