@SewingBees Glad to hear you're back home following surgery.
@nappybrained and @TopOfTheCliff I was also on Filgrastim and got unbearable bone pain. Every time I breathed out I heard myself moan in pain, it was weird. I took loads of codeine before each injection after that, plus missed out day 6 of each of 7 days in the following cycles. Horrible stuff, but it did increase my neutrophils although apparently a lot of them aren't functioning cells when 'told' to grow by Filgrastim (I heard).
How many cycles of EC are you having, @nappybrained ? I had 4, and really did suffer on that combination. I know someone who worked through it, which I find incredible but she felt fine (!!!) how can we all be so different!?
@mesocortical Welcome. I'm sorry to hear your diagnosis.
I am a fellow HER2+++ (hormone negative) breast cancer patient. I also had a large (more like huge) tumour at 11cm, which weirdly didn't show looking at my breasts (does HER2 eat up all the normal breast tissue?) Like you, my lymph nodes were also cancerous (multiple). It's a horrendous shock when you hear things are so locally advanced and aggressive.
I was Grade 3 though, so a bit different to you with Grade 2. I was told HER2 is always aggressive and doesn't exist as 'slow' as Grade 1 unless it's also Hormone positive.
The time between knowing your HER2+++ status and that it's also in the lymph nodes, and starting treatment is really stressful. I had to wait about 5 weeks between diagnosis and the start of chemo (after already having waited several weeks for my initial appt).
To give you an idea, this was my treatment plan, in chronological order:
_
EC chemo x 4 cycles
Paclitaxel 12 x weekly infusions
Phesgo (trastuzumab + pertuzumab) x 18 cycles, once every 3 weeks starting with Paclitaxel
Surgery a month or so after finishing Paclitaxel - full mastectomy and full lymph node clearance levels I-III.
15 days radiotherapy to 5 areas (axilla II-IV, chest wall, etc etc ) once recovered enough from surgery.

I had pCR so continued with Phesgo; if I hadn't, I'd have had Kadcyla chemo/trastuzumab for a further year.
Treatment for HER2+++ hormone negative BC is brutal, but at least the targeted therapies exist now! You didn't mention trastuzumab or phesgo, but if you are HER2+++ you will need a targeted therapy.
