My left hand has three fingers (ring, pinky, middle) in a frozen bowed position at the DIP and PIP joints. I have had blood work, seen a rheumatologist, neurologist and now hand specialist with no diagnosis or treatment plan to date. I have limited use of left hand. I have a history of osteoarthritis, mild in hands and moderate in spine. lAlso, trigger fingers on Dad's side. I'm very worried with no diagnosis and thus no treatment. Any ideas greatly appreciated??
