Was that a 'stuttering relapse'???

Was that a 'stuttering relapse'??? Hey guys, I asked this question before with one of my FB friends and he thought that one moment when my tongue got stiff on the letter 'L' and got an instant block prior to the next letter 'z' didn't mean a relapse, instead, a relapse means constructional stuttering which means if my general speech fluency is obviously deteriorated than previous, then it's called a relapse but my situation doesn't stick with it. My current situation is that, at times I get blocks but generally speaking, my fluency is normal and nobody can recognize me as a PWS and I am not covering my stuttering at all like covert PWS do.
