Greetings, sorry about your pain. Going by your description you have rheumatoid arthritis. To confirm it you should do rheumatoid tests - RA FACTOR, C-REACTIVE PROTEIN,
VITAMIN D3,
VITAMIN B12, AND HEMOGLOBIN AND ALSO SERUM
FERRITIN. these will help you identify if you have RA AND what to do next.
Next Steps
a diet with combination of protein and fat is most recommended. this will help fight joint swelling and exercise like walking and ball catching bouncing on floor will help initially.
