I've got the same
Update: I have done jelqing since then (using my hand instead) and it cleared up by Sunday night :) .
I’ve just got the same problem you have, 2 purple spots on the left side (one more on top the other on the back). I’ve got mine from stretching though (the only thing I did yesterday). I’ve find it a little bit weird cause I didn’t see anyone with injuries because of stretching ? Anyway, I was wondering if I could continue jelqing until it goes away ? That what you did right ?
