“Is testicle injury permanent?”

Hello,
Sorry to hear you hurt a very sensitive part of your body.
But it does depend on the type of injury you sustained. Did something hit
your testicle like a hard baseball or did you trip and fall landing on your
bottom with your legs opened wide? Do you have an open wound on your
testicle?

An easier example would be if one injured their knee (then the injury can
be a bruised knee or a fractured knee or a strain knee ligament or a knee
muscle strain); the knee fracture would need surgery & the knee ligament
strain needs a special knee brace to heal well; but a bruised knee or
muscle strain will heal with local ice and ibuprofen or naproxen & a simple
ace wrap.

With all injuries, the 3 main issues to address are: bleeding control
(apply ice), pain control (tylenol, ibuprofen or naproxen) and infection
control (if there is an open wound). There can be complications of bleeding
(hematoma can form). Swelling is best controlled with local ice and
elevating the testicles (i.e. not walking alot in boxer shorts; jockey
briefs would be good support - but not if too tight and hurts to wear
jockey briefs).

Best to see a physician if you can.
