Sural nerve: Sural nerve runs on the outside of the lower leg to base of 5th metatarsal. It not commonly injured unless you had a lateral ankle injury, such as, an ankle sprain. Then you can have ligament, tendon or even a fracture which would explain the swelling. Either way, you should see a foot and ankle specialist.

See a physician: See a physician, be assessed for DVT to be safe, as damage to the sural nerve can cause decreased use/function after loss of sensation, consider dvt. If no dvt, any nerve damage can cause autonomic dysfunction to a limb and can cause swelling.If you are having significant pain, talk to your physician about complex regional pain syndrome as one of the first signs other than pain is vasomotor change.
