thrombosed vein after 2 days of noob routine?

hey everyone,

after 2 days of DLDs noob routine I had a bump that I beleive is a thrombosed vein. It's almost gone now, but I haven't trained since. I'm not accustomed to random bumps on my dick so I have a few panicked questions.

what'd I do wrong?
is this from stretching or jelqing or both?
how do i prevent it from happening again?
when is it safe to resume training?

all help is greatly appreciated!

i followed the entire routine very closely, including the warm up/down. I soaked in a tub for 5 minutes, then later read somewhere that it should be 10, so i did that and i've been doing the soaks/Kegels daily but afraid to get back to stretches and jelqs til the bump/t vein is totally gone. i wasn't agressive about it at all, if anything i was holding back.

is it normal to have an issue after only 2 days of training?

can't post a pic because it's almost completely gone, but it did feel like a chord and didn't hurt.
what does EQ mean?

I warmed up ina tub for 5 minutes (going forward this will be 10 minutes)
did the behind the cheeks to the left and right, but skipped center cause i could'nt figure out how that would work. did one to each side, timing for 30 seconds. waited a few seconds and did another set. waited and did a 3rd set.
same thing w/ straight down. left 30 seconds, down 30 seconds, right 30 seconds, then 25 cranks. did that 3x
again w/ straight out. again w/ straight up.
300 jelques w/ vaselline, stopiing anytime i got a full erection and waited for it to get back to semi-erect.
skipped the testicle health portion on the first day (actually i forgot...)
5 minute in a tub (going forwrard this will be 10 minutes).
later in the day i did the 100 quick kegels, then 50 five second kegels w/ 2 second rests, then the 1 60ish second kegel

EQ means eretion quality. I had a bump from a vien before and I fine a 10 minute warm up helps and messaging the area were it is bumpy. It went away for me over time and I didn't slow down Penis Enlargement at all and my penis is back to normal.

what's the difference then between a t vein and a cyst, and is there anything i could have done to prevent it? will it happen less as a move forward?

PS - been doing motrin a few times a day. how long should i use it?
