What is joint hypermobility?
Hypermobility simply means that you can move some or all of your joints more than most people can. You may have been aware from an early age that your joints were more supple than other people's. You may think of it as being double-jointed. If a number of joints are affected your doctor may refer to this as generalised joint hypermobility.
Hypermobility itself isn't a medical condition and many people don't realise they are hypermobile if it doesn't cause any problems. It might even be an advantage in sports, playing musical instruments or dance.
However, some people with hypermobile joints may have symptoms such as joint or muscle pain and may find that their joints are prone to injury or even dislocation. If you do have symptoms then you may have joint hypermobility syndrome – also referred to as benign joint hypermobility syndrome (BJHS) or sometimes Ehlers–Danlos syndrome type 3. It may be useful to think of it like this:
Generalised joint hypermobility + symptoms = joint hypermobility syndrome
