I've had an ache in my left breast for a couple of weeks how. Finding it difficult to sleep on left side. Just found a lump when I was rubbing it to ease the ache. On the side closest to arm, quite deep down, in line with the nipple. Ive been unwell recently with flu like symptoms. Not covid. Is this probably just a swollen lymph node or anything to worry about? I can be quite the drama Queen. Ive got a very sore throat just now, neg covid if that's any relevance.
What's the best thing to do? Keep an eye or try get seen by gp?
