Hello~First, I would take an anti-inflammatory, such as aspirin a couple times a day, this will help take the
pain and swelling down. Next, I would see a chiropractor, funny as it sounds, you could very well have caused some of the little bones in your hands to become out of joint and this will surely hurt, he/she can take and x-ray of that area and determine if this is the case; a simple adjustment should have your hand better in no time.
