My vision continues to bother me, I wonder sometimes if it is not optic neuritis and a deeper problem in the vision center of my brain that is effected by MS lesions.  Still trying to get a call back from the MS Center at Carolinas Medical.  I've called six times and left a message on there answering system and have never gotten a call back.  I've actually talked to three people there and never have gotten an answer to any questions.  Once I was immediately put on hold and after waiting over a half hour I hung up, called back and got no answer. THIS IS A MAJOR MEDICAL CENTER IN A LARGE CITY, WHAT THE HECK IS GOING ON! Sorry, just venting a little frustration here while I sit in pain, going blind, waiting for a health care worker to decide that they can help me.
