Hello Doctors,
I had an accident few days ago, and hurt my left side face.. and beneath the left eye, I felt some Numbness on the left side nose and a little part of my left face with with the middle part of my upper lips... there where some swelling but no blue color. I"m in India now and the doctor gave me *Remyline-OD*, and said that would strengthen the nerve... My Q. is: is the numbness will go after a while..?? and is this medicine would help me with my Case..!!
