Hey Sam,
If it's a hard lump, give it a fooking good squeeze/ hit it with something. Could be a ganglion. I have one on my middle joint, middle finger. Grows over a couple of weeks, not really painful and every now and again I can pop it and massage it away (sometimes requires a hard item on it). I think it's where the joint capsule/ tendon sheath has ruptured slightly and then healed in a distended way. It fills with fluid over time. Often called bible cysts (cos they used to wack them with bibles). If it's actual swelling could be an accumulation of 'crap' in the joint (scar tissue etc). I've recently been doing something called 'voodoo flossing' which works bloody wonders and loosening up finger joints and promoting healing. Terrible name and comes from cross fit but actually works!
Anyway, when are you coming up to cheddar?
