Podiatry and or foot care

Patient: About,3 days ago I had to make a 28 mile walk.However,the tennis shoes I wore I realized,during my walk,were not the best for my,walk.I ended up having a very sore,swollen right foot,after I got back to my apartment.The left upper side,of my right foot became swollen.When I saw it,I realized pus had bulit up inside.So,I sterilized a strait pin under fire and used alcohol,on my foot before relieving the pus,with a punture,to the pus area.However,it still hurts some,when I try to walk on it,and a little pus returns,after the end of the day,and I relieve it by squeezing it all out.Do you think Dr.Sharmin,that I need to visit,a Podiatrist..as it still hurts,when I try to walk,still?Thanks alot,Terry.
