I'm a 19 year old female who had a microdiscectomy on the L4-L5 disc about 4 months ago. I had almost immediate relief from the sciatica, and I had been feeling very little pain whatsoever for the past two months (I was only bothered occasionally when lying down). However, the deep cramping in my lower back and a slight bit of numbness in my leg has come back. I'm afraid I began working out too soon after surgery. Should I be concerned? Or should I just rest it for now and wait to see what happens? I'm extremely nervous.
