My fingers normally get infected whenever I pull out a hangnail, but now my finger has gotten infected and I am concerned. It is red and swollen at the tip like normal, but in addition my entire finger is swollen to the point where it is visibly larger than the same finger on my other hand. It also hurts the infected area when I bend it more than a little bit or straighten it, so I have been keeping it in the slightly bent position that does not cause pain for most o today and yesterday. Normally these infections do not worry me but this one has got me worried. Any advice would be appreciated.
