My husband is 33 years old and his left foot is swollen and pus coming out from in between toes , it's hurts to walk and has pain in his calf ?

Need to see his doct: Mostly he has foot infection and need to see his doctor for treatment.

Go to ER : Your hsuband has an infection and most probably cellulitis. Your description is concern for a blood clot in his leg. See a doctor now.

ER ASAP: This can be very serious. Sounds like he needs admitted to the hospital.

Infection: If this was isolated to the toe or 2 toes i would say a rapid appointment with your podiatrist. But with pain in the calf and what sounds like swelling moving up the foot the right thing to do is visit the er - right now

Infection: I agree with dr. Inwood. Seek medical attention now not tomorrow. This can be limb treating and if you are sick, diabetic, ca patient etc it can be life treating.
