Awaiting breast clinic appointment- so worried

Hi everyone

for a few months I've been experiencing a weird sensation in my armpit, that sometimes travels down through my left breast. I visited my GP twice and they have now referred me, however the wait is crippling.

The pain is getting worse, more so when I lift my arm up, but I cannot find any swelling or lumps. My mum suffered breast cancer and didn't have any lumps either, she had a mastectomy and lots of lymph nodes removed.

lately I keep feeling like my nipple is wet/cold. But it isn't. I'm wrecking my brain over it all as I have 3 children (youngest is only 1) it's a tormenting time not knowing isn't it?!

Did anyone experience these symptoms?

many thanks in advance xx
