Hammersmith are one of the most generous when it comes to cancellations in my experience.
I think I would take a totally different approach for the PCNs for which representations have not yet been made to the council. Don't mention the contravention at all and ask only for a discretionary cancellation due to the medical circumstances and provide documentary proof. I'm thinking ahead to a possible tribunal Appeal and this case

One problem is that the council are entitled to remove the discount after 14 days whether you make a representation or not.
We need to see one of the rejection letters, assuming they are all the same, cover up only your name and address.
At the tribunal I would argue that signage is inadequate in that although it is perfectly ok to only have one sign at a location, to put different signs on each side of the road makes it likely that a driver will only take one in. Against you is the fact that you didn't see the 'flying motorbike' sign c. 15 times. I also recently blogged about this sign
