Welcome to Health Care Magic
You should see a NEUROLOGIST
. He/she is the person to test the nerves and muscles. They also have several ways to investigate - eg. nerve conduction studies, EMG (ElectroMyoGraphy
) and so on. They alone can pin point the nerve involved, extent of damage and possible cause. If at all, the cause happens to be Tarsal tunnel, they will give appropriate referral.
You are really clever to have thought of these two possibilities.
The details are not enough to suggest possible diagnosis. Peripheral neuropathy
is usually symmetrical (both sides) / can extend beyond ankle. Tarsal tunnel is generally on one side / it is limited to foot. There are several small facts which will lead to a conclusion by the nerve specialist.
Wishing you speedy recovery
