My Mom is 67 years old. 6-7 years back she had minor paralysis attack on the right side of her face. After two months treatment of medicines and physiotherapy she was OK. Now, from the last 2 years, she is not able to walk properly. She can walk straight, but whenever she wants to take a turn her feet just refuse to move (just like a lock in the feet). She become very nervous for few seconds. After that she slowly moves. From the last six months, she has fallen down 2-3 times in the house due to this. Now from the last week, some white fluid started coming out from her face after every few minutes. This fluid problem I saw earlier in her 6-7 years ago when she got paralytic attack. Rest she is eating properly and looks well. Just she had a walking problems as I explained above. She is going for physiotherapy from last one month. Kindly suggest what is her actual problem and what should we do to improve her condition?
