I am 29 yr female, sometimes while walking suddenly i m loosing control on my right leg for few seconds and falling down , but everything is nirmal in next few seconds. I have experoenced this around 8 times in past 2 to 3 months. In 2008 i had an accident and had an head injury, got swallowing to right side of my head behind ears. Very minute hearing loss for right ear, wad detected in test. My brain scan was done that time, but notjing found in it. I was 5 months pregnant when i had an accident, after that incident i was not able to cobtrol my balace for 3 weeks. I got fully recovered in 3 weeks. There we no any issues after that. Can u please advice what may be the reason for this sudden loss of control in right leg.
