What can I do to alleviate pain after trigger finger infection?

Infection. If you have an infection you may need antibiotics or even surgery. Seek medical attention asap, because an infection could damage your tendons. If you have trigger finger but no pus, therapy, ice sometimes anti inflammatory medication may resolve your problem.
Ice & nSAID's. Ice at the injection site is probably the quickest way to alleviate the pain after a trigger injection. Otc nsaid's are also very helpful. I like to give oral steroid for a few days as well. I nice trick is to take a golf ball and put it in the freezer. Once it's cold, put it on a table and rub the sore part of your hand over the ball. This combines the effects of cold with message.
