Your fingers really shouldn't be hurting like that after a week of resting them. From what you're describing, it sounds like you've got some joint inflammation that's not going away like it's supposed to. Try some aspirin. It's good for joint pain.

If this happens again, you might want to have your doctor check it out. Does rheumatoid arthritis run in your family? If you're at risk for it, it's a good idea to get in the habit of taking a couple of tablespoons of apple cider vinegar per day in a glass of water now, to slow the progression if you're starting to get it.
