I would be the same. I find too that in certain situations, when my stutter gets really bad, my chest has started to become tight/sore. I don't understand why as I've never had this before, at first I thought it was due to my weight but I saw a doctor and they said I was perfectly fine which is not what I was expecting. I've had some great days with fluent speech and I think, "this is the end of my stutter", and two days later I could have the worst experience of my life. I'm not sure what affects it, I think there's too many variables
