Hi all
I had my Covid booster on Sunday 30th Oct, and noticed the next morning that I have a large 'bulge' in the front of my armpit with pain right to the back of the armpit. It has not gone down today, if anything it's bigger.
A Google shows that this is known as an uncommon but possible side-effect of the booster, but I wondered whether anybody else has experienced this, and how long it might last?
TIA
