I had a PLIF in December. This was my second surgery in 2 years. My elderly mom became really ill and I am taking care of her in my home. Im really scared that I have possibly re-injured my back and possibly done something to my L4- S1 fusion. I am also experiencing some pain up higher that where the fusion is...HELPPPPP! I hadnt been experiencing the leg pain and associated cramping/muscle comtractions in my leg until last weekend. I have had to pull, lift and move my mom but she's only 95 lbs. Has this happened to anyone ??? I would really appreciate any input!
