Hi and welcome to HCM
You can injure the joint capsule with what you did and it can swell up like the dickens. Gets lots of fluid in it. And it takes a long time to go down and can leave residual swelling in the base of the finger.
Try massaging the area with an ice cube. Ice Massage
can help to reduce swelling in the tissues. Do as often as you want. After doing the ice massage, try putting a heating pad
on the area so it can get the blood supply going really well and that helps to remove the fluid.
Try "splinting" the finger to rest the area.
Do some finger exercises.
I do hope that you have found something helpful and informative and I will be glad to answer any further query.
