very sore breast almost 2 years post partial mastectomy

Hi , brief question is WLE the same as a partial mastectomy?
In Oct 2006 Partial mastectomy for 1.8cm grade 3…FEC x3, rads X25, Herceptin x18, tamoxafen for 15 mths…Had oophrectomy 7 weeks ago, complicated by ovaries stuck to bowels…

Stupidly ive just found out how unfit i am…I had a bad fall from a horse yesterday, i landed on my affected arm and back, but my breast is very sore and swollen…arm very bruised. …

Im at my caravan, a hundred miles from home…just worried if ive burst something, i remember surgeon mentioning he had filled the space with saline! He actually said he didnt understand how it worked!

Legs and back aching too…defo joining a gym!!

Also how does the lack of lymph glands affect healing?

Sorry for so many questions but has anything similar happened to anyone else?

Many thanks,

Jill
