rheumatism or arthirtis??

scratches head..... what is the difference between these two illnesses?? i heard that even young people get this nowadays... u dun have to be an old grumpy lady to get this.....

recently, i have been feeling pain in the joints... when i am in a cold place.... like just now, i was sitting under the ceiling fan in the living room and i felt pain in my right knee after a while.... then i remembered that when i was in the car the other day, the powerful aircon was blowing right at my right elbow... and i experienced this really sharp pain there as well... wah lau... my mum was right all along.. i am just an old lady trapped in a young girl's body..... :(

oh no... come this thursday, i will be all alone in the office... with ah meow going to shanghai.... so boring... boohoo...
