Does stuttering hurt?

Does stuttering hurt? I posted recently about how my stuttering only began as an adult, and how there haven't been any (known) neurological problems. It's most likely due to drops in blood pressure, as I've seen other people on r/POTS comment. I feel physical pain when I stutter, like my jaw, tongue, lips, and even chest feel like jerking or spasming. I've seen people say not to guess what a person who stutters is trying to say, and I respect that. But trying to speak can be so painful that I'm relieved when someone finishes my sentence when I have a problem. Is it common for stuttering to be painful?
