I'm 62, dealing with this condition since I was 35. No doctor can find what is wrong with me except the possibly of Rheumatory Arthritis Negative. I have very little information on this condition as it is very rare. I've had two knee replacements, spinal fusion and it's starting in my hands, hot pain and swelling. Doctor put me on pretisone for 2 1/2 weeks to see if I respond and then wants to put me on methotrexate. Is there anyone out there like me. All my test results come back better than average.I show symptoms of Lupus, Sjorgrens Diease, Rheumatory Arthritis, Ostiporosis. But they kind mark it with a test. I've recently spent $10,000.00 in test and it came back unnormal. That's better than normal yet my joints are being destroy and it's getting worse quicker. Please let me hear from you, if there is one other person like me anywhere. Thank you and God Bless you.
