I have arthritis. I feel far too young to write that sentence. But every time I tell someone I have it – in the base of my thumbs – the usual response is they have it too, usually somewhere different. Feet, knees and hips seem to be the common culprits.
It turns out arthritis, which is actually an umbrella term that covers 100 different medical conditions that affect the way the joints work, is the most common cause of chronic pain.
