Am I hypermobile?

My mum seems to think I'm just being paranoid and its just because I'm young and flexible except I've read up on it and I seem to have a lot of the symptoms and I don't want to have it but if I do I want to know about it. So heres the evidence some may seem to have nothing to do with it I don't know but I took them from this article(http://www.arc.org.uk/arthinfo/medpubs/6... article
I've had severe growing pains
I fidget
I sit in my chair in the most bizarre ways because I can never get comfy and often get called up on it by friends
I'm not sure how but I always walk in an odd way
I bruise very easily
I write very scruffily
I can't stand still for very long or my hips and legs start to ache
I can do a lot of the stretches and earlier today looked up some yoga moves and did some of the harder ones such as the 'standing forward bend', 'wheel pose', and the 'One-Legged King Pigeon Pose' (to be continued)

(continued) also when I play sports (especially badminton which I enjoy so much I have recently joined my towns team) although I feel absolutely no pain during the excercise around two hours after play I begin to feel the aches and the next day I can be assaulted by joint pains so bad that I have to take a cocktail of painkillers just to crawl out of bed, I can't find any other explanation as to why this would hurt me so much and nobody else I know, it certainly can't be normal but I think my mum thinks I'm either faking or its gone because I used to complain of pain a lot but now I just take drugs and get on with it because I know she won't do anything, so I guess what I want to know is is my mum right to think me paranoid or could there actually be something wrong with me?

It does appear that you have a lot of the symptoms listed, but to be accurately diagnosed you need to see a doctor. Written things are good guides, but that is what they are...guides. They point to the possibilities and you determine from that if you have enough in common to seek a true diagnosis and/or treatment.
A funny story comes to mind...did you ever hear of the hypochondriac that always read medical books and died of a typographical error?
It's good that you're seeking knowledge, but don't be your own doctor....use the guidance it gives to either dismiss the possibilities, or follow through with a doctors visit. Good health to you, luv.
