I have been suffering from finger joint pain and swelling for one month. It appears on any finger, stays for about 2-3 days, swells, reddens and then disappears. The pain is, however, very deadly. I have also been diagnosed with progressive systemic sclerosis since past 8 years. Right now, not on any medication and don't find any previous symptoms like heartburn, skin tightening appearing. My uric acid and rf seem to be fine. Reports are normal.
