Oh Chipper, I am so sorry I didn't see this sooner. 
Best to let a doctor lance it. Doing it yourself can lead to more problems for many who try. 
Sure there are some successful lancing done at home, but when done by a doctor, your chances of further infection are greatly reduced. 
I am glad you are feeling better. 
I am so very sorry about your dad. I never felt my age more than when I had to start facing the loss of my parents. 
Please take good care of those feet. Still on the same course of antibiotics?
