I am a 66 yo female. About 10 days ago, while I was sitting down I had a sudden, severe pain shoot down my leg from my left hip to above the knee . It only lasted about 30 seconds. Today it happened again while I was sitting down. This time it lasted about 90 seconds and was extremely severe, bringing me to tears. It started on my left side right below the waist, then went downward and curved to the front of my leg, ending above the knee. My first thought was sciatica, but I didn t think that was in the front of the leg. For the last month or so I have been having paresthesia in my toes, particularly on the left. I saw my doctor for a check-up last week and he said it was probably a nerve problem and if it got worse, I would need testing. Any thoughts would be appreciated.
