<s>[INST] my hands are numb at night,but numbness starts on the ulna side. I do have osteo arthritissymetrically in alljoints. The numbness I think is related to the angle of my lower arm to the body. This has been long standing and is getting worse in spite of usins a nightbrace. Thenumbness starts on the little finger side and spreads across so that the palms are affected as well as the fingers. I have had nerve conduction tests and have been told that I do not have carpal tunnel syndrome [/INST] Hi, thank you for providing the brief history of you. A thorough neuromuscular assessment is advised. As the numbness is in the little finger it could be due to ulnar neuritis. As this is the common symptom due to inflammation of the ulnar nerve. Also, performing strengthening of the triceps muscle will help improve the biomechanics of the elbow and surely your numbness will subside. I have seen cases of similar complaints and usually it's due to ulnar neuritis. Patients respond well to physical therapy. RegardsJay In Chat Doctor.  </s>
