Sounds like a recipe for disaster.
Might be risking a penis fracture which is a big ouch!
Jelq should help.
Some extenders actually claim to treat Peyronie’s disease and claim to be FDA approved. I was unable to verify this on the FDA's website or find a site with a reliable link that could verify this.
You should not be doing anything for a while.
Didn't you just injure yourself?
However long it takes for your penis to get back to normal healthy function, I would wait that period again with rest.
(Example - took 1 month to get back to normal erection - wait another month before even starting anything.
And I would still recommend a doctor check up before starting anything in your case.
