My knuckle has suddenly (as of this morning) become red, itchy, burning, swollen, stiff. I also have a red spot on the palm of that same hand with similar symptoms. I am currently being treated with a 2nd round of anitbiotics for an infection in an incision in my leg. What can I do to help the knuckle? I really want to try to do something on my own vs running to the doctor within a few hours of symptoms, however it is quite bothersome.
