Hi Domanique, I read your other post and put them all together. The breathing and problem swollowing could be part of thesame thing. Yes it could be from some type of auto immune problem. CREST causes esophagus problems which makes food get caught going down. Also breathing problems. I was diagnosesed with asthma and thn several years later was told it wasn't asthma it was COPD. Now the rheumy I have thinks I might have scleraderma which also attacks the lungs. You need to bring this up to your rheumy. Have you been diagnosised yet? What was you ANA? I'm just curious about the pattern. Not that it means everything but I have a lot of the same symptoms as you mentioned ad I am the only one on here that I'm aware of with a nucleolar pattern. Anyway please be sure to discuss this with your Rhummy I think it will be very important to your diagnosis.
