I have tingling only while chewing at the right side of brain where the injury 5 cm to injury  site and this happens only while eating. And that too only while chewing rice or tough grinding food.I had recent head injury and even after three days I have no symptoms sir. No headache, no vision loss,no numbness, no dropping, only tingling at the right side of brain close to trauma site and too only while eating. Any severe neurological disorder that I might be suffering from?
