Last night I was driving home, and suddenly I got a dull, pulsating ache in the lower left side of my back, kind of in my hip. It got more and more painful until it was more of a deep stabbing pain, it would come in waves and it felt almost like a pulsation or throbbing pain. It would do a few throbs at a more dull, less painful level, and then randomly do one or two stabbing pains, painful enough to make me groan out loud. This continued for around 4hours until I fell asleep! I woke up this morning and it didn’t hurt anymore.
Does anyone have any idea what this could be? I told myself if it still hurt this morning then I would take myself to A&E, but now that it’s stopped, I’m just left feeling confused
