scare using penis pump

I recently got a pump, still practicing with it. A couple of days ago I guess I broke a cardnal rule. I had an erection and applied the constriction ring. After a few minutes the erection was getting soft. So I pumped it up again and used the ring again. Then I developed a puffed up area like a welt. I imediatly removed the ring. The swelling went down. Now there is some brusing...wich I understand, but there ia also a small lump where the swelling was. Do I just need to relax and leave the poor guy alone for a week or so and let it heal just like any other brusing, or should I get this checked out? I will be 6 years Cancer free May 5th this year.

Thanks,  Jim

Thanks!

I was prescribed a vacuum a few years ago and i decided to try it out while my wife was out. I have never laughed so much. I filled it and it was stuck on me and the vacuum would not release, it was too funny to see to make me worry lol, left it alone for 20 minutes and it came off. They thought it was hysterical at Urology when i told them, needless to say, i gave it them back :)))
You just have to laugh when you can, Bob.
