Hi Ann,
I think Lucca would want to examine Ellie again not just to see if there has been progression in her SM symptoms, because of course there can be, even in the space of a few months, but also to consider what combination of meds or introduction of new meds such as Steroids might be necessary.
If Ellie can barely put her leg to the ground, then she must be in considerable discomfort and I would imagine that even the most basic things like going outside and squatting to perform her toileting must be difficult for her. As you say, you know how unpleasant the pain can be after knee surgery, but of course if Ellie had surgery, the pain would pass after a period of recovery. Ellie would then be able to enjoy her mobility again, at the moment she is constantly disabled and constantly in pain with her LP.
I understand that there are a number of factors to consider, such as her age and her heart condition, but despite these other considerations, Ellie might well be with you for a good few years yet and if she doesn't have LP surgery, then how good might those years be? I suspect that this is why Lucca is pushing for her to have the surgery.
It's such an easy thing for him to say however when he has no emotional attachment to your baby and he can just view things in a very practical and quite dispassionate way. Sometimes that is the sort of advice we need though!
Try to get Ellie's SM meds sorted out as soon as you can (so that you can see the wood for trees remember?!)
I'm not sure my hubby would push a bright pink buggy around with a dog sitting in it either!
