Thanks for writing to H.C.M.
I have gone through your query regarding paralysis
of right vocal cord for last 7 days. You have told about endoscopic findings but other pathological tests as- Blood sugar, X-Ray chest etc are if normal than it is most likely viral inf of recurrent laryngeal nerve
. In such situations with due concent of your treating doctor steroids
may be added for short time to get good results.
