Hi I noticed a small clear blister along one side of my finger near the top, a couple of weeks ago. It stayed clear but the skin was taut and it was a bit sore to put pressure on. I really noticed it burning when I wore heated glove liners for motorcycle riding. The last couple of days it has gotten more sore and changed color to a rusty hue and i thought it broke but the skin has just recessed. It was very sore with a numbing and burning today. I don t remember doing anything to it and thought it was some type of bite. I have been in the AZ area so not sure. I had thought of a brown recluse spider but don t really know the symptoms. What do you think?
