Joints hurt

I noticed that every time I'm out in cold damp weather my joints will hurt terribly later that day or at night, sometimes even the next day. I've been having joint pain in my knees since I was little (I'm 18 now) but over the years it started happening in my elbows too and now it feels as though the pain spreads to some of my knuckles when it hurts really bad in my elbows. I'm not sure if I get these pains when the weathers changing because I don't pay enough attention but I wouldn't doubt it. I'm wondering if this could possibly be arthritis? a
And if it is, does that mean the pain will only get worse as I get older, because it's already unbearable, and will my joints be completly useless by the time I grow old?
oh and it's a different joint that hurts each time, sometimes one will hurt then it'll stop for a bit while another one hurts then they'll switch back all in a matter of a few hours, I think that's kindof strange..
