The location “upper left back” could mean near the shoulder blade or could mean the top of the lower back area (thoracolumbar junction or where the chest meets the lower back).

Tingling sensations typically are from irritation to a sensory nerve. If this area is near the puncture site of the epidural catheter, the symptoms could be a result of irritation to the local sensory nerve that exits out of the spine at that level (the medial branch of the posterior nerve).

If this is the case, these symptoms are nothing to worry about. Over time (three to six months) the symptoms should diminish.
