Purple patch

Hi guys just a little worried here but 3 weeks ago after doing my 10 min jelq I noticed a small bloody purplish patch appeared just under the foreskin scar, however no pain. Next day becoming a scab. I took a week off and today I jelqed it happened again, a purple patch on the same spot! I don’t know whats wrong because I don’t apply too much pressure at all or should I let what ever I burst
Heal a lot longer?

Thanks in advance guys
