Sounds like you definitely have something going on there with that big toe. Can I suggest something that might help? In our house, we are great fans of apple cider vinegar. I try to keep the real stuff around, with the 'mother,' but regular apple cider vinegar will work, too.
Warm the vinegar to as hot as you can possibly stand it on your toe, and make a hot compress out of a clean rag or some gauze. Soak thoroughly with that warm/hot vinegar and apply it to your toe. Yes, it's not going to feel great, but I have seen many times that this hot apple cider vinegar will draw out an infection in about a day, depending on the severity of the infection. My brother was able to treat himself with this method. He had a terrible red streak going up his arm from some infection or injury, and within a day and a half, the red streak was gone and his pain and swelling was almost nill.
Keep that hot compress on there and wrap it in tape, vetrap (we call this stuff horse wrap and it works GREAT) or whatever else you have on hand to keep this compress in place. I would change it every hour and put a fresh HOT one on, re-wraping it to keep it there.
Right now, I am nursing a spider bite on my foot. Dang thing bit me yesterday, felt like a knife! No, I don't know what kind of spider it was, but the pain was terrible! Anyway, I am currently using plantain and hot apple cider vinegar to draw this out, and the redness/pain/swelling is almost gone. It was really bad yesterday.
Hope this helps you. You may want to consider using the plantain, too.
