Hello everyone. I’m a 21 year old female, I have recently found a lump under my armpit, nearer to my back, it’s slightly smaller than a pea, its hard, immobile and painless. I’ve had a lot of swollen lymph nodes under my armpits in the past 5 months but they are always oval shaped, quite big and visable, some painful some not and they go on their own so I know what they are and what to look out for if I have one of those as I’m used to them, but this one is different, it’s really round and small so I know it’s not a lymph node. I will book a drs appointment, but wanted some opinions and advise. Thanks
