右側頭皮與臉頰麻痺原因不明，神經內科檢查結果如何？-神經內科

有關臉麻頭皮麻（已就醫檢查）？

醫師您好，因這兩個月右邊的頭皮及臉頰區域會陣陣發麻、偶爾也會在鼻子附近有麻感。
目前沒有糖尿病/高血壓/心臟病（都檢查過。
另外還有兩頰會痠痛，到神經內科就診抽了血甲狀腺沒有問題、做了腦波（沒有問題）、神經傳導有問題，但醫生沒說什麼問題，便讓我去做腦波核磁造影，在單子上看到：Routine blink reflex study revealed no pick up right r2 and r2’but noral at left sideSuspect right CNV pathway lesion後來回診看造影的報告告知沒有異樣報告內容如下：The supine position superconductive 1.5T brain MRI with surface coil was performed for this suspect trigeminal neuragia patient. the pulse sequences including axial T1WI, T2WI, SWI and FLAIR. coronal and axial thin 1mm slice thickness posterior fossa T1WI and T2WI studies.no intravenous gadolinium was given. the axial functional brain images ( DWI and ADC maps) were also performed. Findings:1.no focal mass lesion, no abnormal signal intensity change nor midline shifting seen within the brain parenchyhma. 2.no acute intracranial hemorrhage is seen.3.the intracranial vessels still show normal flow voiding.4.the ventricular size is normal 5.clear appearance of bilateral paranasal sinuses and bilateral mastoid antri. 6.bilateral cerebellopontine cisterns and parasellar regions show no focal mass lesion; the cisternal segments of bilateral trigeminal nerves are well-seen. no external compressive mass effect nor displacement occurs.7.the axial functional whole brain images ( diffusion weighted images and ADC maps) show no acute ischemic infarction, no acute inflammatory lesion nor tumor mass lesion. 8.the 3D intracranila T.O.F MR angiography shows no vascular malforamtion or saccular aneurysm. no apparent focal vessel luminal stenosis or flow interruption occurs. Impression: bilateral cerebellopontine cisterns and parasellar regions show no focal mass lesion; the cisternal segments of bilateral trigeminal nerves are well-seen. no external compressive mass effect nor displacement occurs. the axial functional whole brain images show no acute ischemic infarction, no acute inflammatory lesion nor tumor mass lesion. the 3D intracranila T.O.F MR angiography shows no vascular malforamtion nor apparent focal vessel luminal stenosis redundant course. suggest correlate clinically and regular follow up.目前我還是不知道為何右臉頰發麻又頭皮發麻，醫生讓我先吃藥，看到藥單上開了一顆mecobalamin並註記經檢查證實為慢性多發性病變。
請問1.多發性病變不是蠻嚴重的事嗎？
但醫生完全沒提到。
2.如果我吃了藥依舊發麻我應該再去他處再次檢查嗎？
3.主治醫師說有可能是我天生就神經反應慢，有這個可能嗎？
4.因為前陣子剛好去檢查眼睛，眼科醫師也有說我右邊瞳孔收縮比左邊慢，會是相關問題嗎？
醫師很抱歉，因為真的很困擾很不舒服，現在真的不曉得該怎麼辦，還請您給予建議解答，謝謝。
