As well as expressing my thanks for all your good wishes, I also have to give a massive shout out to the NHS.
DH had an accident at home (a fall) on 3 August. Trip to A&E revealed a brain issue - not related to the fall, so just a complete, and fortunate, coincidence. CT and MRI scans, then cerebral angiograms followed, and now treatment is complete. (There will be a follow-up in 6 months or so, but otherwise that should be it)
Without exception, the people we have dealt with throughout this process have been helpful, courteous and friendly - despite evidently being busy.
We are so very lucky to have it - even if it is currently underfunded and under pressure.
