Probably infection: The blister may be a sign of a developing skin infection. the sore may be infected also. Wash both with antibacterial soap such as dial and then apply neosporin. Do this 3 x/day and seek medical care if the area becomes larger or develops into a boil ( a tender swollen area of skin) seek care immediately
