Burning stinging pain down right shin into top of right foot with a tight/burning feeling in both calfs top of right foot is swollen/discolored cause?

Cause is hard to. Determine. Any history of injury to back? Seek out a neurologist who will need to run some tests and likely try some medications. Will need nerve conduction study at very least. How long ago was knee surgery? If recent then see dr. That performed the procedure.
