as i said above i had a lumbar puncture a week ago, because i was suffering with bad headache and lose of sight in my left eye, which only happened when i was bending down then getting back up! since having the lumbar puncture, they found my pressure was high, and took some out for testing and then took my fluid out so that i was on a normal pressure! but now i have very back back pain and it does not matter what i do, lye, sit stand walk anything! it still hurts!! ios this normal??? i am worried something has been damaged when they did the lumbar puncture! can anyone help me or give advise???? thanks
