Hi I am a 26 years old neonatal nurse and I am worried sick. A few months ago I had this pain in my left underarm that wouldn't go away initially I thought it was due to getting my second COVID 19 vaccine so I waited for 6 weeks and now the pain is still there. It feels like there's something stuck in my armpit (like when you put your drink bottle under your armpit when you try to carry lots of shopping bags to your car). I have been feeling weird sensations in my breasts but there are no visible changes or bumps/lumps. I have recently discovered clear nipple discharge that come in very very small amounts although it seems to be coming from the left i have noticed it sometimes from the right nipple too. I have finally built up the courage to see my doctor about it today and she has referred me to a breast Clinic to my local hospital after she said there's a possible swollen lymph node in my armpit. I am worried sick I have pain in my left shoulder, upper left back and my neck too, I don't have any other lumps but why would she refer me if she wasn't worried. Please help.
