Patient's question:
Right-handed writing suddenly becomes weak, then improves after a while, and then repeats this pattern. What could be the reason?Doctor's answer:
Hello, this phenomenon may be related to upper limb muscle nerve dysfunction. Medications that nourish the nerves need to be taken for treatment. If symptoms persist during rest, an electromyography test is required to rule out the cause of nerve damage. It is also possible that it is related to cervical spondylosis compressing the nerves. Through the above tests, if abnormal findings are discovered, timely symptomatic treatment should be administered to restore normal function of the upper limb.
