RLS is ‘restless leg syndrome’. This is a condition that causes constant fidgeting and movement, most commonly in the lower part of the body.
If you’re one of those people who ‘can never sit still’ and is constantly bouncing their leg up and down under the table, then chances are that you may have RLS.
Now RLS is not necessarily painful and might simply be felt as an ‘urge’. However, some people say that it does feel like pain and discomfort, in which case you might wish to see a doctor. Recent research suggests that low dopamine may be the cause.
