Two years ago I developed unexplained swelling and stiffness in my right knee. When labs were done, the ana was positive (critically high) along with critically high scl 70 and high level of rnp. Since then, I have developed silent refux, narrow esophagus and asthma. My gi dr wants to do a "swallowing test". He suspects scleroderma. How concerned should I be at this point?
Hi, I m Chat Doctor.  Your investigations are showing that you have scleroderma. I advise you to see a rheumatologist as soon as possible. This is a difficult disease to treat, if late Hope this will helpmate care
