When I was first diagnosed with VM in Feb 2016 they needed to perform a lumbar puncture. This resulted in me laying on my side for the doctor to insert the needle. When he removed the needle from my spine he caught a nerve. On and off I have had back lower back issues, nerves getting trapped or sever back pain. I am now 12 weeks pregnant and I am suffering more than ever. Has this procedure done permanent damage and will it affect me carrying/during childbirth?
