The main time I think of health is when I don't feel well, odd

My hands are really cramped, painful, stiff and hot (anyone who knows me knows I have hands cold as a corpse, always). The center of the pain is in my middle finger. It's like it's out of joint, cramping and tensing. I've been in pain all day long.
I get this sort of thing when the weather turns damp. But it normally lasts a few hours at most and was never so bad as today.
Typing hurts, but I think it's helping to move the synovial fluid + heal my joints. It could be arthritis.
I've had it checked out with a doctor before and he said it was lack of iron. I tried taking more iron into my diet, but it didn't seem to affect me. And now it seems like my symptoms and the severity of it have changed. I'll wait and see how I feel by tomorrow.
