What does it mean?

I recently got test results with Rheumatoid Factor of 520.

I am having muscle weakness and pain as well as pain in joints.  Especially pain is in feet and hands, sometimes knees and leg muscles.  Having trouble walking because of excruciating pain and a feeling of weakness.
I have trouble with stairs, especially going down.  I have trouble getting up from a seated position.

I was referred to a nuerologist ( because of a family history of ALS) and a rheumatologist.

I have been seen by the nuerologist (series of blood and urine testing which has not come back yet) and yesterday had an EMG.  This doctor gave preliminary opinion that I do not have ALS (Thank God!) but still wants to examine all results when he receives them.  He also thinks I should see rheumatologist ASAP.

I am still waiting for an appt. with rheumatologist.

I am wondering what diseases could be indicated as possible by the high rheumatoid factor?

I am glad it does not look like you have ALS as I am sure that takes a lot off your mind.  Yet, you are in pain and suffering while awaiting a dx and treatment plan.  I can tell you that a high rheumatoid factor can be associated with several conditions but is most frequently associated with rheumatoid arthritis.  Getting in to see a rheumatologist is the right thing to do.  Please let us know what you find out.  How long until your appt?
