My dad is 66 years old. He has too much pain in his knees, ankles, feet, elbows and other possible body joints with inflamation and redness at various parts of body. Also, he has decreased a lots of weight. In addition, he has high uric acid for which he is taking some homeopathic medicine for last sometimes. he has gone for the having Rheumatoid Arthritis. I am very worried with his drastic weight loss. Can you suggest what should we do ? What could be the other possible scenarios ? Thank you,Ranjita
