Swelling, arm heaviness and tingling - no lumps

Hello, i poated recently symptoms of sweats, heaviness in left breast and fatigue. I seen the nurse and she felt no lumps so i felt reassured but she ordered bloods just to check.

My bloodwork showed my platelet count to be slightly raised and she said something about my red blood cells not being the normal shape, i wish id asked what this meant but i didnt.

My main symptoms were breast heaviness and tenderness and also in my armpit, it felt swollen. For the past week i have been having a heaviness in my left arm (feels like someone give me a dead arm) and tingly sensation in my fingers. I went back to the gp today and he done another examination he also confirmed he cant feel any lumps on the surface and said i have a fullness down the left side of left breast and he could tell i was tender under my arm, he said the new symptoms are concerning and has sent an urgent referral.

I suppose im just wondering if anyone has had thee kinds of symptoms and no lumps and if so do you mind sharing with me what your outcome was?

Thank you for reading :heart:
