Hi:
At only 9 days post-op, I'm sure this is perfectly normal. Back surgery takes a long time to come back from.
A week after my micro-d L5-S1, my leg felt like it was on fire and felt swollen (it wasn't swollen, just felt like that). Hurt quite a bit.
It was all due to inflammation.....and aggrevated the nerves. The doc put me on the 6-day steriod pack (methylprednisone, 4mgs.). In 3 days I felt 95% better. It took the swelling down.
Ask your doctor about the steriod pack.
I'm sure you'll be feeling much better in a few more weeks. The back takes 6 weeks to stabilze after surgery. Don't worry......this all sounds normal.
Hope I was able to help alittle bit.
Sue
