That last part is the worst part. Given you'll have already had nothing to eat in the run up to the one they cancelled.
That pincushion feeling does go, eventually.
When they thought I would be having the scan, they put in a canula. This had to be taken out before I left. The nurse who put it in, obviously had plenty of experience. My main problem at present is moderate tummy pain, that is keeping me awake and making me feel queasy.
Most of the time I was in a waiting room with a young lady who was obviously very ill, and therefore, and understandably not talking. The last two hours there was a gentleman and his wife. His wife was a patient. and he was an expert in constructing electric trains. He knew lots about international train timetables, and was very witty on other subjects, which slightly lightened the mood.
