Weird knuckle pain

[JacksWeather]

When I seem to grip the disc with my index finger better than usual, like stronger grip, make the disc rip open the grip, grip strength focused into hand. The FRONT of the knuckle closest to the finger tip hurts, its a burning type of a pain. Not in the joint, but like the surface of it, maybe even at the skin. It seems serious if whatever I'm doing happened every throw, like its not just stretching a muscle, or twisting funny, it seems like its when I'm gripping better than usual, feels like the joint bone is splintering microscopicly or tiny amounts of tendons or ligaments are ripping off bone or something.

Anyone have any experience with this type of pain or any idea whats going on? Luckily its a very infrequent pain, I'm just a little worried its going to happen frequently if I improve my grip strength.

the disc is still slipping/sliding and bursting blood vessels.

pre-throw grip strength and mid throw grip strength are different things.

often, better pre-throw strength yields weaker mid-throw strength.

Hmm, not sure if I adequately explained where the pain is. It is on the side of the finger/knuckle that is the same side of the finger as the fingernail.

I'm wondering if you knew I was talking about that side of the knuckle, because I don't understand how sliding of the disc would irrate the opposite side of the finger. What you said about busrsting blood vessels seemed to make sense because the part of my finger that hurts turns red a little bit, even though it directly doesn't come in contact with any other part of my hand or the disc.

it's still the same answer.
