Pain in armpit/ boob

[MyLifeNow20]

Not sure where to post. Stressing me out recently but the pain has been going on for 3 ish months on and off. Recenetly its everyday.

Pain in left under armpit, down my ribs on the outside and into my boob. Feeling a bit run down so could be due to that. Cant feel any lumps.

Could be muscular? Lifting children on that side, mucking my horse out using that arm more so...

Should I go to doctors? Dont want to waste their time

Why do you think having a health issue checked out is wasting a doctor’s time?
Breast issues should be checked.

Badly fitting , old bra?

I kept waking at night with breast pain. Worked out it was a certain bra at a certain time of the month causing it and it's been fine since I switched to non under wired.

Something I’m not seeing being talked about much is that the vaccines are giving a lot of women (temporary, completely harmless) cysts - could it be that?
