I am 19 years old and am 9 weeks post op froma two level lumbar fusion of the L4-L5, L5-S1 vertebrae. The recovery from this seemed to be going well but then recently for about the last week or so there has been great pain around the site of surgery. Along with this some of the symptoms which the surgery was supposed to help and did have returned such as pain down my legs. I did trip over not so long ago and wondered if this may have upset the surgery or whether this is just a normal part of the healing process. Any advice would be greatly welcome.
