Bloody tap or bleed: Since you're able to type this question coherently, I gather that your health didn't suffer after the lumbar puncture, so that would probably rule out a cerebral bleed (hemorrhage) as a cause of the blood cells in CSF. Most likely the RBCs came from a "bloody tap" - trauma to blood vessels of the back from the needle. Normally, no vessels are damaged, but doctors are not perfect! Hope all is well.
