My Wrist/hand click with pain

im only 20. well my wrist/hand is messed up or something. i work at a restaurant so for a while i thought my wrist/hand was aching because of carrying heavy plates and stuff all day but about a month had passed and id figured it would go away but it hasnt. ive only been working there 2 years only in the summer

first off, when i put my hands together, palm to palm, every finger lays against each other, but my left index finger, its bent back, its not extremely bad but you can see how its bent backward and its not straight. thats only visual thing i can see about it. when i move my hand up and down i can feel a click on the back side of my hand, if you follow your index finger till you reach your wrist, thats where it is. its hard so i think its a bone or something i dunno. i also experience 2 more pains. the second, palm side of my hand if you follow your thumb to where your wrist meets, it hurts there. and on the palm side where your index finger meets your palm, it hurts there. other than that i get aching when i carry stuff with it. its not THAT bad i still carry stuff with it, its just that annoying ache where you know something probably isnt right.

anyway, what would you people think it is. nothing, a sprained wrist, a pulled tendon, or do you think i could have broken a bone or something? i wouldnt think so since i can move everything and theres no bruise. thanks!

edit: oh and when i lean on it for about half a minute, it goes numb. seems kinda fast
