It's easy to look back and think 'why didn't I notice earlier?' (you know, before my cancer got to Stage 4), but the truth is that hindsight is 20/20 and when you're actually living through these symptoms they feel so unrelated and random.
Annoyingly, I now have to use a crutch because they're worried that the cancer has weakened my hip/pelvis/leg on the right side enough that I could quite easily fracture something like my femur. I really detest crutches - they are gangly, awkward and make my hands hurt. But use them I must I suppose - it's probably less cumbersome than having a fractures femur.
Today I faced a major fear of mine (having a cannula inserted), offered to bite a nurse, and experienced some kickass cool technology thanks to the NHS.
