Hi and welcome,
The problem with toes is that they are easily banged, squished, crushed, dinged, cut, damaged etc etc and we soon forget about kicking the coffee table, stepping on the kids toys, tripping over the cat, how uncomfortable or ill fitting our shoes really are etc etc until sometime down the road it comes back to remind us...
Feeling odd sensations in your peripheral limbs upon waking or after walking a lot isn't what would typically be suggestive of a neurological condition like MS. The descriptive 'buzzing' is often used for an internal vibration or invisible tremor which is associated with a lot of different medical conditions eg Essential Tremor, peripheral neuropathy, Parkinson’s disease, MS as well as Anxiety and also as a side effects of mental health medications antidepressants or anti anxiety.....
You seem to recognise that this sensation exacerbates your anxiety and or you get worked up over it, which i assume you mean you freak out or have a panic attack so there is the potential that this is related to your mental health and even if anxiety isn't the cause, it would still be in your best interest to see a therapist or psychologist to learn alternative ways to react to it which is less distressing for you.
Hope that helps.......JJ
