Pain post spinal fusion. Leg as well!

Hello , I had a minimally invasive spinal fusion at l5-s1 due to spondylolisthesis grade 2(unstable on X-ray) and nerve compression at the same level, I had a surgery two months ago and while my mobility has become better and I don't have much back Pain , I have a sharp pain in the back of my thigh and sometimes also in the foot which makes me wonder if this is normal, my X-ray at 4 weeks looked fine without any hardware malfunction , the same foot is painful which had symptoms before surgery for two years I am also going for physiotherapy along with manual therapy of trigger points which is helping but Complete pain resolution hasn't happened, both my doctor and physio have mentioned right muscles in the same leg as well
