You might try applying lemon oil where it hurts. Lemon oil contains limonene, which has been shown in animal studies to relieve pain and inflammation. When nothing else worked, I used lemon oil for relief from shingles pain and it seemed to also spur healing.
Lemon oil is available in a small bottles at the aromatherapy rack of a vitamin or health food store. It is a thin oil that absorbs quickly into the skin and can be applied repeatedly to good effect. Be careful as it will sting if you get it into any scratches or sores or into your eyes.

Poor dear. Well, hope your finger gets better.
Three pieces of advice:
1. See a doctor.
2. Seriously, see a doctor.
3. Did I suggest seeing a doctor?
That’s what happens when you say, “Pull my finger”.
Sticking it up too much at liberals?
Seriously, it is most likely tendons or nerve ( sub as carnal tunnel syndrome or similar) related. Does it improve with rest? Does it go numb or tingle at all?
