welcome to hcm, i really appreciate your concern, yes RA can cause discoloration in fingers and hand movements. The symptoms that you have are likely to be due to rheumatoid arthritis. Other causes can be gout, inflammatory diseases like SLE, bursitis, fibromyalgia, etc. For proper diagnosis, some of the blood tests are advisable like- 1. Serum calcium levels. 2. Serum Uric acid levels. 3. Serum Creatinine. The rheumatologist will do the needed investigations for proper diagnosis. Arthritis requires expert care with various disease modifying drugs (Imunomodulators). You can start these drugs after discussing with your doctor. I would like to give some diet tips which might be helpful to get rid of these pain. Often the elimination of certain foods such as the following will help greatly: Dairy products, with the exception of plain yogurt with active culture Citrus, with the exception of lemon and grapefruit Alcohol Meat including beef, pork, and lamb (other sources of protein such as chicken, fish and beans are less likely to promote inflammation) Vegetable oils (continue using olive oil and the essential fatty acids flax seed, sesame, pumpkin, sunflower oils) I would also like to give some advice to make the life better and to fight with these pains- Do regular physiotherapy of joints. Hot fomentation to decrease the joint stiffness Hot bath of Epsom salts (magnesium sulphate)-Magnesium has both anti-inflammatory and anti- arthritic properties and it can be absorbed through the skin. please let me know if you have any further queries. thanks. regards
