I have a burning sensation to the top of my toes and the left side of my head, behind my ear, burns when touched. ?

Paresthesia: Causes depend on the exact location of the paresthesia sensations, but typically include a physical nerve injury type condition (e.g. A nerve entrapment or some type of pressure being applied to a nerve directly or to the spinal attachment of that nerve), or a disease condition affecting the nerves (e.g. Neuropathy, diabetic neuropathy, multiple sclerosis, diabetes, and others).

Your symptoms: Are not related. The burning sensation in your toes can be neuropathy. I suggest you see your pcp and discuss your symptoms.
