Advice please! 8 weeks post MD - L3/4 laminotomy/facetectomy

Hi! Long post, I’m sorry! Hope everyone’s having a great weekend! I had surgery just over 8 weeks ago. Everything was great, my left leg numbness/tingling/leg pain had virtually disappeared. I recovered for about 5.5 weeks before returning to work (hybrid 2days in office, 3wfh). Started PT about 4 weeks after surgery. My PT has been so impressed with my progress that they’re about to “graduate” me and he even gave me the okay to do light walking on the treadmill only starting this week, which I did my first one today.

I’m nervous because the last few days, I’ve noticed the numbness/tingling and shooting pain in my butt reappear (left side). I also have been having pain on the right side of my lumbar spine, but I thought maybe that was me just overcompensating to protect the left side. I’m currently at about a 6/10 on the pain scale and I’ve resorted to taking a pain pill tonight 😿. Should I be concerned? Is it possible I re herniated? Should I reach out to my surgeon? I’m so scared.
