Which pulmonary function test are you referring to with those numbers? Did they do MIP or MEP on you (specific to neuromuscular diseases)? And is that the order in which they occurred, getting better each time?
You might also have more than one thing going on. Did they check any basic levels, such as thyroid, B12, Vitamin D, etc.? Why did they think MS? Do you have peripheral neuropathies in your feet, hands, or face? If so, get that B12 checked right away, and don't accept that 400, for example, is normal. It's not, especially when you have symptoms!
When was the last time you had an ECG (12-lead of the heart) done? Have you had an echocardiogram done?
Does your weakness fluctuate? Does it get worse with activities and better with rest? Fatigable muscle weakness is the hallmark of MG.
It's good for you to see a neurologist to at least rule some things out. Hopefully between them and the rheumatologist, you can get some answers!

Hi Annie. Thanks for responding!
I'll try to answer as many questions as I can but I admit I haven't quite wrapped my brain around all the tests yet. Also I have preexisting fibromyalgia so that complicates things a bit.
The rheumatologist does not think MG, she thinks MS. Pretty much all of my doctors have suggested MS except the MS specialist. He said it's possible to have MS with a clean MRI, but it's not possible to have MS, have the symptoms I have, and have a clean MRI. Also in my exam he said I was showing signs of muscle weakness but not signs that there's something wrong with my brain.
The rheumatologist does know about the elevated CPK since it came back on her panel of tests. She is now listing "myositis" on my chart under "diagnosis" but she still wants the neuro workup because all of my autoimmune tests have been negative.
The three pulmonary function tests occurred in that order. I don't know specifically what kind of tests they ran but I doubt they did anything specific to neuro diseases. Pulmonary was my first stop on my mission to see every specialty in the hospital and they didn't know what they were looking for then. The first one was done by my GP at the local Navy clinic. The second one was done there a couple of weeks later when an inhaler failed to make significant difference. The third was done at the Naval Hospital. It's possible that the third was the most accurate (the test seemed more involved) but anecdotally I did feel as if it was gradually improving.
They did a full metabolic panel several times. Thyroid etc is fine. They said no nutritional deficiencies and they check my Vit D with regularity because of the fibro aches and pains. I don't have the tests so I don't know how they came back exactly, just that they were within normal limits. I have a tiny bit of tingling in my feet sometimes, but I've always had it with the fibro. There's none in my hands or face and it's been going on for . . . 13 years? So no one is really considering that a symptom of this latest mystery.
I had an ECG at the ER when the breathing trouble started. That and the echo were normal.
The symptoms are all better first thing in the morning. It seems that every new symptom I've had has followed this pattern-- I get really stressed/tired/overworked. The symptom hits suddenly and with some severity. Over time, with rest and lots of time in bed, it gradually improves. Day to day I notice that I wake up with almost no symptoms-- vision normal, able to eat normally, etc. Then as the day progresses the symptoms get worse.
They haven't tried any treatment yet but my GP gave me prednisone when I told him it felt like my throat was swelling shut (that's how the weakness felt to me at first) and it seemed to help. Whether that was real or placebo effect I don't know.
