Sensory loss when you experience a loss related to; sight, hearing, smell, touch, taste and spatial awareness. So the bits related to your feet make perfect sense in relation to sensory loss:
"Sensory loss is the most frequent of all neurological findings in MS. It is present in 90% of patients at some time during the clinical course. " Source: Rajas Deshpande, ... George P.A. Rice, in Neurology and Clinical Neuroscience, 2007
As for the other things, I'd talk to your doctors about those (all of it really). Is it possible that you could be still grieving or going through a depression? I ask because a lack of excitement in things that are normally considered exciting can be a symptom of depression. MS can also cause changes in mood and processing, give its affects on the brain so the rest might be possible (that's really a neurologist's territory to answer).
And yes, I have experienced (and still do) several different types of true sensory loss (lost all sense of proprioception in my legs, the sense of their position, as well as pressure sense, or anything beneath the skin really sort of the opposite of what you have, if I don't move or touch them my brain forgets they are there lol). I have not had the flat emotional affect you mention though, if I did, my first thought for myself in that case for would be depression, since MSers are more predisposed to depression it has a higher likelihood for me, and depression can affect this. Depression has 100% affected this emotional/pleasure aspect for me before, and treatment for that relieved it in my case. If I was certain that depression wasn't a factor after checking with my doctors and MS-specialized psychiatrist (our clinic uses this type of specialist in cases of depression and off-label MS symptom management meds), then I'd talk to the neurologist about it to make sure to keep him in the loop, since new symptoms can sometimes be a subtle indicator of relapse. Also, when my neuro hears of depression-like symptoms they screen for it with tests, since it can also be caused my some DMTs and that might warrant a change of DMT.
Best of luck in identifying the source! Please consider this response also to this similar question you posted:
