Welcome back to Get Fit Guy. I'm Kevin Don.

Recently, the weather here in the United Kingdom has been pretty wet and thundery.

My hip and lower back have been causing me significant discomfort.

So, what's the deal?

Is the change in air pressure or humidity causing my joints to flare up,

or is this just an old wife's tail? We'll dig into that and some more pain myths in a moment.

But first of all, how about we define what pain is? According to the National Institute of Health,

pain is an unpleasant signal that something hurts. Okay, I think any of us could have written that definition. It's a complex

experience that differs greatly from person to person even between those with similar injuries

or illnesses. It can be mild and almost unnoticeable, or it can be

explosive. Typically, it comes in one or two forms. We have acute pain. She usually comes on

suddenly and is related to a specific injury. It's a protective response to damage and also

usually time limited. If not, it ends up becoming the

second pain type, which is chronic pain. This is persisting pain and involves environmental

and psychological factors more than it does biological protective ones. Pain occurs when

no susceptors, which are specialized sensory cells, send an electrical

impulse or signal to the brain. This is usually in response to a stimulus, such as heat in the case

of being burned or localized tissue damage in the case of an injury. Pain also has an overlap with emotions,

such as fear, anxiety and anger, which can amplify pain experience. There are also a bunch of

chemicals called neurotransmitters that have a role to play in your pain experience. Glutimate,

for example,

heightens sensitization and makes pain last longer.
