I have the exactly the same thing, and am 25 years old. It has been happening on and off for 5 or 6 years. Normally once it happens, it will come every few minutes for a few hours or up to an entire day.
The pains are sharp and startling, and enough to make me forget about whatever else it is I am doing at the moment. Also, I'm not sure if it's important to note that a couple years ago I had the flu, and a temperature about 103 and it seems liked the pains became more severe and that there was less time between them. Actually, any time that I have been sick and had a fever; it seems to exacerbate the pain.
Has anyone went to a doctor with similar symptoms?
it would be helpful for a doctor to answer because i have the same problem i get a burning sensation along with mine and i have back pains in the midsection of my back and my tailbone
