Warm sensations down leg?

I woke up with warm sensation coursing down my left leg. No pain or weakness. Anyone experience this? I am 9 weeks post-op and hoping it is a good sign rather than something bad. Any thoughts?

I’m 3 yrs out from my 2 Spinal AVM removals a 1 bleed. My family DR told me if your concerned contact your surgeon.

Before my surgery I had that warm, wet feeling on my legs. It felt like water being poured down them. I have had it once since my surgery, but I keep hoping it means nerve feelings are coming back. It seems to happen when I work out (as weak as the workout is) or walk more than normal.
