sudden onset lasted all day Sat, stopped, returned today, all day. Every 30 seconds a stinging, like a bee sting lasting 5 seconds in lower leg above ankle. No trauma, no swelling, no bruising, not tender, just literally like a 5 second bee sting that I have timed every 30 to 45 seconds. Can't drive because it is so bad it causes me to jerk leg just like you would if being stung by a bee.
