I have a throbbing pain and a sensation of a heartbeat, in my lower left back concentrated around top of my buttocks. Same position every time. It happens daily during various hours of the day. Usually it's 2-3 heartbeats that I can feel, along with pain. Sometimes it lasts for 10-12 seconds with severe throbbing pain. I just feel like screaming at that point of time. After those couple seconds passes, its all normal like nothing ever happened.
This pain started around 2 months back and stayed for around 1 week. I had 3 long duration pain one day and the next morning had my head spinning (hardly could stand) and went to the ER. Doctors checked for Kidney stone but couldn't find any. I didn't have the pain after that until 2 weeks when it started again.
I have an appointment scheduled with a neurologist. But any advice would help me a lot.
