Throat/neck pains

I am six weeks post mastectomy without reconstruction and have had a seroma which is going down, but not completely gone yet. 
My pathology confirmed stage 1 grade 1 (no lymph node involvement) so my next step is hormone therapy. 
I am having a weird symptom that I’m unsure about. I will call my BCN next week, but looking to hear from others too. I am having pains (not constant and not awful) around my throat and under my jaw. If I massage under my armpit the pain goes up the front of my neck. I’m wondering if it’s either nerves or lymph stuff healing (or seroma being re absorbed by lymphatics??) 

Anyone else had similar? X

Definitely worth ringing your BC nurse. We have all sorts of weird sensations after surgery but best to check with your nurse ,always reassuring to get their advice . Hope it settles soon .
