If tapping on inner ankle reproduces & worsens the tingling in arch of foot - is this always tarsel tunnel or can the problem be coming from higher up? also have tingling in calf. thank you?

The only true definitive way of determining the integrity of a nerve is a nerve conduction velocity test. Tapping on the nerve is a very good clinical test. Sometimes history and exam is all that is needed to evaluate and access a problem. A proper diagnosis is required to provide a proper treatment plan. Neurologist would be helpful in determining location and cause And thus treatment.
