My antiextractable nuclear antigen test came back with rnp antibodies 0.2 and Smith antibodies 0.2. My ANA IFA test came back negative. But I have a host of symptoms that seem to point to something autoimmune . or at least fibromyalgia/chronic fatigue . My biggest concern now is the swelling and pain that has been going on for over a year. I have swelling in knees, elbows, ankles, left side of stomach, and face. The swelling fluctuates during the day. It s worst in the morning, and decreases during the day, but never fully goes away. I also have problems with stiffness and trouble walking at times. I have a reddish rash that appears over my nose and cheeks and when it fades it turns scaly. It looks like a malar rash, but any tests for ana or rheumatoid factor always come back negative. The only positive bloodwork I have has been chronic low potassium and low vitamin D which is now being supplemented. I ve done an allergy blood test that only revealed allergies to types of trees and pollen that would relate to seasonal allergies. Foodwise milk was the only allergy. A urinalysis came back with Protein 1+ and a specific gravity of =1.030. I am now on Metoprolol for a heart rate that reached 130, but after an ekg and stress test a cardiologist has said that my heart is fine. The metoprolol was also able to stop the tremors I was having, which were more like seizures, although a 2-day eeg was negative for seizure activity. The only other medication that stopped the tremors was a Prednisone taper that I was prescribed for frequent severe headaches. I ve done an abdominal ultrasound that was negative, and also a chest x-ray that was negative as well. Is there any way to make sense of all this to figure out the underlying problem.
