I have a diabetic foot which has had ulcers and blisters on it. Now my 4th toe which has the joint taken out over ayear ago is red & swollen & hurts quit abit what I do?

You didn't really learn from your previous experience. YOU ARE A DIAB ETIC probably type 1 insulin dependent. If you don't want to lose your whole leg, get yourself to a doctor, hospital, emergency ward, whatev er BUT DO IT NOW!!

Get to your doc. Better safe than sorry.
