Hi Tigwig
I had the same thing for about 10 months and ended up refered a neurologist by my GP to get it checked out. It ended up being nothing drastic at all, just something resting against something it shouldn't, but like you it was driving me nuts, so they ended up giving me a small amount of botox to freeze the nerve. The relief was unbelieveable (it's amazing how something so small can be so annoying!) Ofcourse it wears off after about 4 months, but it's worth having it done at the local hospital for me. Although they only did one eye, so I have one gorgeous wrinkle free eye and one normal 28 year old one! Stress can ofcourse make these things worse too, so I really hope things get better for you soon x
