How do i tell the difference between shakiness in legs and shakiness in neuropathy.

May not be very easy: It sounds like your question is asking the difference between shakiness in the legs due to weakness of the muscles (such as after heavy exercise?) vs. weakness in the legs due to lack of neuronal control or innervation? Your best bet is to get a neurological examination since other things needs to be noted physically and by history before arriving at that sort of conclusion.

Shakiness: Normally neuropathy causes numbness, tingling, or sometimes a feeling of burning or impaired temperature sensation. Shakiness is not just a feeling, but a visible movement, which can be caused by tremor, tired muscles, changes in blood sugar or blood chemistry, etc. Neuropathy symptoms do not change with movement, shakiness in the muscles probably would change with standing or climbing stairs.
