What should i do about my 'broken' knuckle?!

I'm pretty sure i've done some significant damage to my knuckle!.!.i punched a desk like!.!.3-4 days ago!.!.and my middle knuckle on my right hand has had a consistent swelling to it, i can bend/move my middle finger, but there is slight pain when i make a fist!. There is a tremendous about of pain when i slightly poke/push on my knuckle!.!.and when i do touch it, i can feel the pain through out my hand/wrist/arm!. it is a numbing/burning kind of pain along with normal pain (im not sure if that made sense!.!.!.) And also, if feels squishy when i do touch it (i cant touch it for more than 1 second without it hurting!. and the pain from one touch last for maybe 5-10 seconds after i take my finger off of it!.)


I think it's broken, but i've also heard it could b a tendon problem!. so my question is!.!.!.if i did go to the doctor, what would he/she be able to do!?!? would they just give me a splint that i could buy at the store!? (because i dont have health insurance, and idk how much it would cost, depending whether they did an X-Ray or not)!.

SO
Would seeing a doctor not be worth it!?
Should i just wait for it to heal!?
Should i go to the doctor right away!?
what would they do!?!?

I appreciate all the help Www@Answer-Health@Com
