Was the cause of this an antibiotic? Could there have been any other cause? Did you have any surgeries or injuries around the same time the symptoms started? Did you ever have LASIK eye surgery?
Thought I replied to this, odd. I don't know what antibiotics they may give after surgery. The reason I asked is some people develop severe corneal neuralgia that has/causes whole body symptoms - central sensitization, hyperalgesia - which sounds somewhat similar to small fibre neuropathy.
