Talim hopefully you are feeling a bit better. I know you've been through a big surgery but the flap shouldn't hurt, neither should your tongue really (post op yes. but this far out - almost 3 months - no). I get that it might be tired but usually by week 8 you should not be experiencing actual pain. Muscle strain yes (my tongue gets tired too, by the end of the night if I've talked alot I get a bit lispy and achy but nothing painful). SO I am going to go against the grain and say have them check it again and maybe ask for a scan. hugs and take care.
