Hello

I am a 29 year old female, very fit and healthy, 3 children.

I have been having left breast pain for 3 weeks, with a tender armpit, I have now had some swelling on my forearm thats sore to touch, tingling and slight numbness that comes and goes down my arm and finger tips.

My gp reffered me for an ultra sound under 2ww, as she could feel small 2 pea sized lumps - although my breasts have lots of little squishy lumps it feels like! Im really concerned about the pain thats spread to my under arm, forearm, shoulder, back and generally everywhere in my body that comes and goes multiple times per day. 

The skin around my nipple has a winkle/puckering type look but that comes and goes its not always there and its the same on my other breast. I have also had loose bowels movements for 12 days, my bloods have came back fine but I know they cant detect anything sinister. Any reason for any of this? I am 5 months post partum, but I have never experienced anything post partum with my other 2 children. It feels like muscle, nerve and bone pains throughout my body that comes and goes all day. 

Thank you
