Bubble after using extender

I’ve recently bought an extender and I used to use it for a few hours a day. Now frequently I have a bubble (full of blood) after a couple of hours (I take a break every hour). I wait for it to be gone and when it seems fine, I start again. Again after a few days, another bubble.

Has anybody ever experienced it?

Where is this bubble forming? That doesn’t sound great to me

It’s on the glans. Doesn’t sound great to me either

I let it go, let the glans recover like there’s nothing and after a week or two, back again with the extender and back again with the bubble after a few days.

I tried to start with some jelqing too to make it better, but the problem remains

I’d imagine jelqing with this kind of injury wouldn’t do anything but make it worse. I’ve seen bubbling as a result of prolonged extender use online but never experienced it personally. My advice would be to take a break until it’s completely healed, and adjust your routine to avoid this in the future. That might mean using the extender less frequently or for shorter duration which could hinder gains, but nothing slows gains more than injury.

By “jelqing” I meant before using the extender; when I wait for it to be recovered, I do nothing.

I’ll try again to wait for some time, maybe a month or two.

My routine consists only of: warm up, jelq, extender.
