Finger injury- Splitter/forkball

Hey guys, my Index finger or more specifically the big knuckle on my index finger has been bothering me for over a week now. It started from moving from a thinner grip on my splitter to more of a deeper forkball type grip. I’ve stopped throwing it altogether yet it hasn’t gone away yet. How long should I wait until I would know it is something serious or something that will just go away?

Thanks!

is it like

rough skin kind of?

No, it’s not the outside skin, it is in the knuckle itself.

its not just the splitter if it still is there

sounds like a nasty blister

keep with the splitter
make your grip smaller

use the two seam grip
grip it out side of the two seams

jus dont let your finger get worse
