I have a open sore on the bottom of my little toe. it would appear that it is an infected toe but no pus or swelling . very touch sensitive and painful. Could it be MRSA? my circulation is poor and some loss of feeling in the toes is present. what is going on?
Hello. Feet are generally the most undeclared for part of the body. It is in constant contact with the ground from which it can pick up millions of bacteria, one of them being MRSA. Note that I said ONE in a million could be MRSA.  You have a sore in the toe mostly due to repeated trauma or single bruise on the foot and have ignored the injury, or you have a foot ulcer secondary to diabetes. There are multiple causes for an ulcer/sore.  But since you complain only of pain and no swelling or pus I do not think it has reached the stage of infection. MRSA is not your worry now. Kindly give a cold pack and observe for two days. If the pain does not subside it is better to consult a surgeon, and he will have a better idea if it is a concealed infection. Even if it turns out MRSA do not panic as we have sufficiently large antibiotic ranges to treat these resistant bacteria.
