It has helped pretty much anywhere I have had inflammation. I still get some edema and tenderness above my knees around where the tendons attach. Yes to the dry cough, I have been diagnosed with asthma for several years. I was told I had 'mild apical scarring due to prior granulomatous disease' but no answers as to what that was. Now I know it was probably autoimmune, possibly Sjogren's. The other diagnosis has been Undifferentiated Inflammatory Arthritis, which means they don't know which category it falls into yet. I am thankful for a rheumatologist who is most concerned about treating the inflammation and takes the time to see what is going to show up over time.
