Hey - do you guys mind if I jump in on this, since I have something similar happening? Buzznerd, you seem very knowledgeable about ANAs. I've had positive ANA results since 2012 and I've been in the same boat about doctors dismissing this. I've been to 3 neuros recently, one diagnosed me with plexus neuritis, and the other two said he was wrong, but that I could have something auto-immune, but they are not willing to dive further into it. Like, "Yea, you could have something auto-immune, but here's the door, be on your way now, scooch." One neuro literally said to me when I said, "Well, if you don't think this is plexus neuritis, then what do you think it is or what should I do?" he said, "I don't know either." Then he took blood for lyme disease (results next week).
Also, I said, "what about the abnormal EMG results this neuro who diagnosed me with plexus neuritis?" he said, "Those results could happen to anyone, they don't mean anything."

Yes, he literally said that. I cannot trust him EVER - never going back to him.
My symptoms now are left shoulder stinging pain (bad!), left deltoid/upper arm pain (stinging, deep) with occasional twitching, left painful elbow when I press on a certain point, left clavicle pain (new symptom, only when I touch it), and left forearm (on the inside) twitching (constant hot spot).
My right hand is still "sunken in" around my thumb knuckle, snuff box and a little between the thumb and index finger - seen and acknowledged by ALL my doctors, but none have any idea what it is. The muscles seem to still be there though. Have watched this sink in slowly over the last year. Some sensory feelings, with twitches, and a different pinch grip, that is just off (thumb and index finger grip).
So here are my ANA results, with dates, from Germany. Anyone have any ideas?
May 2012ENA = negative
ANA-Fluoreszenzmuster (florence pattern?) FLUMUS = speckled
ANA (IFT) = 1:160 (positive)
C-ANCA (EIA) = negative
ANCA (IFT) = negative
p-ANCA (EIA) = negative
Oct 2014 (these originally came back negative, but the lab sent a correction of positive)
ANA HEp2-Zellen (cells) = positive
Pattern = homogenous
ANA HEp2-IgG = 1:160
April 2015ANA HEp2-Zellen (cells) = positive
Pattern = homogenous
ANA HEp2-IgG = greater than 1:80 (did not specify the value on this report)
There was also another positive result in between 2012 and 2014, but my doctor then just said, "yea, it's positive, but does not mean anything" and I switched doctors, but did not get a copy of that lab report yet.
(PS - I am very happy for you, BFSBurger, that you received a thorough check up and explanation. I am sure you know how valuable and rare that is now-a-days.)
