Sir, i met an accident in 2011 and was prescribed eptoin , The same was tapered slowly and since September 2012 the same has been discontinued completely. After six months for the last 5-6 days i am feeling a little uncomfortable in walking, there seems to be lightness and it is not perfect. What can be cause of it? i consulted a neuro physician who has in turn prescribed Duhap for 15 days, is it advisable or should i look for a second opinion?
