Hi all.. I came across this forum while googling "pain in armpit but no lump"... and it's reassuring to see many women have been experiencing the same. The thing is, I had my booster vaccine 4 weeks ago and I'm wondering have any of you who posted more recently have had the same? It's on the side I got the injection... I'm of course imagining the absolute worst. I can't get an appointment for my gp at the moment due to this damn virus... Thank you for reading!
