Have your doctor check it out. They can generally do something to help you if they catch it early enough.
Depends on age. If past 60 could be Arthritis. If younger could be Carpel tunnel. Likely not Tendonitis which is usually in the upper arms.
Sounds like it could be a little of both. Baby the finger as much as you can. Heat is soothing, and topical analgesics should work well. I always use Blue Emu. It's expensive, and I don't know how it works, but it does. No smell, no grease. Just, a few minutes later, you realize the pain is gone.
Stop flipping off 0bama when he says “let me be clear”?
Stop giving people the bird.
You might have pulled it. Or, you might have a small cramp that’s sticking around. See a doctor if it persists.
Get a clavicular resection on the affected side. If you’re over 40, you’ll feel new. It’s a lot of chiseling of bone, grinding, and reseating of you tendons, but it’s where almost all wrist, hand, arm, pain originates from due to nerve entrapment in the shoulder. To know for sure, does the rotation of your arm seem to affect the pain?, such as twisting a doorknob and pulling / pushing at the same time? Do you feel stiff when pulling a shirt on?
Middle finger pain? Give it a rest, stop picketing the White House for awhile!
BTW - I went to my doc for a pain in my rest, he said carpal tunnel and I got a brace. A few months later I went o my chiropractic type guy for my feet/knees. He asked about my brace and I told him, but said it didn’t seem to be helping much. He did his goofy tests - turns out my elbow was out of it’s socket! That was awhile ago and it does okay now, until I try to lift a heavy car battery or something. I take lots of things the doc says with a grain of salt now.
Canucks' bad behavior earns 8-1 spanking!
The muscles that largely move your fingers are in the lower arm. So this probably isn’t a muscle issue.
Probably nerve or joint damage. You mentioned “equipment.” Do you use heavy equipment that vibrates? You may have bruised the cartilidge on one side of that joint. Or caused trauma to a nerve on the side that hurts.
Or it could be something else entirely.
Short version: You need an xray of the joint at issue.
Some other posters have mentioned shoulder issues. Possibly. There is a lot of tension and force transmitted through the arm when you grip something, and a slight misalignment up top could express in your hand.
If the pain persists, see a doc...
You may well have trigger points in your forearm. Trigger points in the forearm refer pain to other places and can refer pain into the hand. For example, many instances of carpal tunnel pain actually turn out to be TPs in the forarm in both the flexor and extensor muscles. Of course, you could also have tendonitis and/or arthritis in those knuckle joints too, as you state.
I suspect you may have TPs in the flexor digitorum muscles. TPs in this muscles can send fairly sharp pains (almost a burning pain) to the inside of the fingers. This TP can be caused by overuse of grasping things, just as you mention.
Look for TPs in the upper forearm and they’ll usually be fairly deep. Using the thumb of your other hand, push inward/massage any really sore spots you find. Don’t over do this. Massage for a couple of minutes about six times a day. It may take a day or three to remove the TPs.
Let me know how you do.
Take two Advil and call me in the morning.
If it doesn’t affect your trigger finger or your shooting, don’t worry about it.
Try some Blue Emu, I use for back and neck pain, it works for me. It’s worth a try.
Also harvest some stinging nettles and apply the sting around the affected finger and pain areas, you can google "medicinal use of nettle" for further info.
I used to have the same problem.
I quit playing with myself (and the problem disappeared)
Just kidding.
I had the same problem and someone suggested that was the cause but it was probably because I slept on it wrong some night or sprained it at work and it just lingered for a couple of months.
Some sprains actually take longer than others to heal.
I don’t know if you have carpal tunnel symptoms, but FWIW, here’s my experience with typing on a computer keyboard to completely avoid carpal tunnel:
When typing, keep the angle formed between the back of your hands and your forearms either 180 degrees (straight) or not much less, but preferably more than 180 degrees. To clarify, place both hands on the keyboard on the home row, with the tips of the fingers touching the keys on the home row, the normal starting position for typing. Move both wrists up while leaving the fingertips on the keys. That’s the comfortable angle you want between your hand and forearm.
If you lower the wrists and lift your fingertips off they keys, that’s the painful hand-forearm angle. Twenty years ago, doing heaving typing, I started getting carpal tunnel symptoms and figured this out by accident through just doing what was less painful to be able to work. People tip their keyboards up facing them, and they position the keyboard lower than their elbows. Both of these keyboard positions force the hands to bend back. You want your hands to bend forward, so keep the keyboard no lower than your elbows; higher than your elbows works nicely. You can also tip the keyboard away, i.e., top rows of keys lower than the spacebar.
I have never experienced any problems since adopting these positions, even to the point of typing all day. If one is tired, not hunching forward with the head and neck is important to avoid a stiff neck.
Nix the arthritis theory. Look down the connective tissue pathway (tendons, etc.)
