All excellent answers,but how old are you? If you are a diabetic or have poor circulation for any reason, then the infection in your toe needs expert attention.
i'm 27 I'm not diabetic, but I think I may have poor circulation because I have been suffering alot with the cold weather lately I'm wearing all the clothes I own plus a hot water bottle down my back and I cannot get warm I think it must be poor circulation but I might be wrong??
