Arthritis: resulting in inflammation in the joints can make it painful and/or difficult to move joints. Your symptoms sound severe if you are having difficulty moving your fingers all day. Evaluation by a rheumatologist, specialist in arthritis, may be helpful in determining the cause of your problems and preventing worsening of the condition and resulting deformity or disability.
