I'm 14 months out. For the first seven months or so, I'd get random pangs of pain that felt a lot like the kind you get when you're too close to a heat source. There was also a lot of random tingling and 'electric'-like sensations.
I had a huge section on the inner portion of the right pec that was completely unable to feel temperature changes whatsoever--I remember getting ready to put on icy cold lotion and bracing myself only to experience nothing at all--and that didn't fix itself until about 8 months in. Now that same area has full tactile sensation, as well.
I'd say I have about 85% feeling along my scar lines, too, in the sense that I can feel very light touch as more than just a pressure sensation.
My right nipple graft somehow has a lot of sensation, too, but it was a little thinner than my left one. My left nipple is probably the numbest thing on my entire chest. I can only feel that there's pressure on it when something's touching it.
So yeah. I can feel a feather gliding along everything but my left nipple at this point. I'm not sure if I'll ever get any sort of sensation back in that area but I'm happy that everything else seems to have come along.
