Over The Past 4 Weeks I Have Had Swelling In

Over the past 4 weeks I have had swelling in feet and ankles bilaterally with pain and decreased range of motion also in both knees and wrists and elbows. Cardiologist ruled out heart disease interfering with walking sleeping and work. Really bad in the morning. Rheumatologist cannot see me for 3 weeks. What can I do for pain relief???
