In June, after an impressive effort to raise $70,000 of the $110,000 needed, Edmonds had the 20mm cyst removed from where it was wrapped around a vein in the middle of her brain.
She said she wasn't scared. "I was so fed up with the cyst that I would quite happily die trying to get it out.
"I had to get it out. I couldn't be a decent mother, I couldn't work, I was just living in a prison of my own body. My son would fall over and hurt himself and I'd have to ask him to stop crying before I could comfort him, otherwise the noise would just trigger my symptoms."
She returned home a week after the operation, prepared for a year-long recovery. "I don't have headaches or head pressure. I have energy in the mornings," she said.
Edmonds still experiences "brain fog", but hopes that will subside.
Her conclusion: "Trust your gut. I knew there was something terribly wrong with me. I just needed somebody to help me. I needed somebody to take me seriously.
"The most traumatic thing wasn't brain surgery, it was fighting for an answer, fighting for an MRI - I fought tooth and nail the whole way and I'm exhausted now."
