I suggest you increase the dose of Gabapentin to five tablets a day. Take two tablets in the morning, one at lunch, and two tablets in the evening. If it does not help you, you can take tablet Pregabalin 75 mg four tablets a day. Take two tablets in the morning and two tablets in the evening. If it does not help you, you can take Amitriptyline 25 mg at bedtime along with other medicines. A nerve conduction study is a test done by a neurologist. It measures the electrical properties of the nerve. I do not whether the situation is temporary or not as there is no obvious cause. But steroids can help you to reduce inflammation. You can consult a neurologist for having a physical examination and nerve conduction studies.
