I found a small lump in my right breast a couple of months ago. It's quite solid and small and roundish and doesn't move freely. It's just below my nipple and I can pinch it between my fingers and see the outline when I do. It hurts a bit when I do that but I think that's just the skin around it being pinched. 

So that's in my right breast. Recently I've also been worrying about my left armpit seeming a bit bigger/fatter than my right one (I've gained nearly 2.5 stone sine first lockdown so kinda thought my armpit might just be fatter. Also I've been getting pimples/green/yellow topped spots under my left armpit (the bigger one). 

So, both things I mentioned are on opposite sides so it doesn't seem obvious that they're related. I've made 2 gp appointments but I've been really tired lately in a morning and have overslept and missed both. I experience quite hightened anxiety and just thinking I'm being paranoid
