3 weeks post op Tummy Tuck don't feel anything? Is it normal?

I'm 20 days post Tummy Tuck with muscle tightening and since I had my last Lymfedranaige massage (today) I don't feel my muscles that tight and sensitive anymore.I don't feel them that tight to stand up or anything else at all.I started walking straight today.I semi stretched by accident sometimes after waking up, I walk around, I do small things at home,little singing and I really don't feel my muscles anymore.I also started sleeping on my side after 10 days.Is it normal? Did I messed something up?
