thanks guys! it turns out my own diagnosis is, uh, a little messy; the ophthalmologist I originally went to thinks I have horner's & I'm getting shunted around a little while I wait on the sfemg & bloodwork results. The neurologist seemed pretty convinced, but the ophthalmologist really isn't buying it, so... I guess we'll see?

honestly at this point the not knowing anything for sure is worse than any of the potential diagnoses lol.

thanks again though! all your responses are really helpful.
