I have been having problems with my upper eyelids twitching alot. I also athritis in my sacroiliac joints and neck pain and terrible pain in my feet when I walk. I tested positive for ana. I don't understand what that is nor do I remember a number. The doctor is sending me to a rheumatologist but, it is hard to get an appointment. I'm 53 years old. Can anyone tell me what all this could mean?
