Hi, I have suddenly developed complete numbness in left big toe and urination frequency - 3-4 days. 40yr old female. otherwise good health, excercise 2-3 times per week. bilateral ovary removal last November, and HTR. Ski accident 18 months ago and labral tear to right hip. have seen hip specialist last year, but doesnt think severe enough to operate. mild moderate lower back pain from accident but having regular physio. Why a sudden loss of sensation?
