A little numbness in the right hand is a personalized problem, because both hands can be numb, and it can even manifest as numbness in both hands. Its symptoms are simple, but its etiology is more, and may be related to the cervical spine and peripheral nerves. Numbness in the right hand needs to look at the numbness site, if the whole arm is numb, not because of sleep pressure caused by acute numbness, from the Western medical point of view, mostly seen in peripheral nerve problems, such as cervical spondylosis, ulnar neuritis, etc.. A cervical spine examination should be done. If the paralysis is caused by ischemia, the onset is more acute and generally intolerable, such as feeling the pulse at the wrist and not being able to touch the pulse, it may be a vascular problem, whose onset is more acute, and all the above cases need to be treated at the emergency clinic. If the numbness is caused by posture, changing the posture can relieve the numbness. In case of discharge-like numbness in the back of the hand, both left and right hand numbness need to be seen and imaging tests such as MRI can be done for further differential diagnosis. Therefore, slight numbness in the left or right hand is not a serious symptom, but it should be noted that if it continues to be unrelieved and gradually worsens or if there are discharge-like changes from the cervical spine, further examination is needed and timely medical consultation is required to avoid delay.
