i ve had trouble with athletes foot for some time, because my lifestyle calls for boots to be worn daily. that being said, i recently noticed my foot becoming excessively sore, and swelling. thinking back recalled my large breed dog (140lb) had stepped on my foot while wearing slippers, n brushed off the pain. last night while examining the foot, i squeezed less than 1/2 teaspoon of puss (estimated) from between what would be index and middle toe. can this be treated at home?
