I'm curious, have you had testing for Sjogren's Syndrome? My PN pain started with eye pain too. It felt like there were tiny needles sticking in my eyes, this progressed until I was constantly blinking and I now know that the cause of my eye pain and eye distress was dry eye symptoms caused by Sjogren's. I also have small fiber sensory and autonomic neuropathy caused by Sjogren's disease.

The eye muscle could be because your eye is excessively dry and it is causing the eyeball to stick to the eyelid. I've had this happen and it makes you panic because you think you've gone blind in one eye. And Liza Jane has a friend who had severe dry eye caused by Blepharis which is a condition that develops in some people due to dry eye causing the eye to blink spasmotically.

If you haven't been evaluated for Sjogren's, I'd personally advise it.
