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

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