hi doctor,
I am 34y/o woman. for the past 8 months, I have been experiencing a sharp and excruciating tingling/spasm in my calf that lasts for only 5 seconds. The longest I have had is like 12 seconds. It used 2 or 3 time in a week, but recently, I get it more frequently. Let's say 4 times in a day for at least, 4 days in a week. What could possibly be the cause.
