Tomorrow will be 3 weeks since my L5-S1 TLIF. I am doing pretty good, completely off pain meds except 2 Tylenol PMs at bedtime. I am walking about 4 miles a day. I was feeling the area around my incisions yesterday (it was MISS and there a 2 incisions, one on each side of the spine), well..it is completely numb right in the center. No tingling or pins and needles, just no feeling. I can run my nail down my back and the feeling goes away as soon as it gets to that area. Is this normal or should I call the Dr. office tomorrow? I don't remember reading anything about this. It makes me a little worried.
