How can you tell if a blister in your foot is infected?

How can you tell if a blister in your foot is infected?

SImple means: You need to identify why the blister developed and eliminate that problem. Then, the keys are to cover and protect the injured area with dressing changes every other day to allow healing. Remember that inflammation (red, hot, swollen and tender) are important parts of healing and do not necessarily mean infection. If the wound is healing, it cannot be infected. If it gets worse, see a doctor.

How can you tell if a blister on your foot is infected?

Signs/Symptoms: A blister that is infected typically will have some drainage that is purulant (pus-like) and will be associated with erythema (redness and heat). The redness may be on the blister as well as the surrounding skin. Swelling is present, and it tends to be sensitive to touch. If in doubt, have your doctor check it!

My husband is diabetic and he walks a lot the other day I noticed he had a blister on his foot what can we do to avoid blisters from getting infected?

Hey-Good Pickup: You are a STAR as one of my former mentors, Dr. Henry Kaminski would always say. You've just identified one of the most important things diabetics can do (aside from watching their sugars & taking their meds) to prevent complications. Diabetic foot care requires special education, footwear, & above all, VIGILANCE and DILIGENCE. Talk to his doc or nurse & get the facts. Good luck you STAR you!

Had a large blister on the bottom of my foot and popped it. It now has a red ring around it, the skin is really hard. It is itchy. Is it infected?

Possible: It's possibly infected with fungus or yeast. It's probably not a bacterial infection from your description. Apply topical lortisome (antifungal cream with hydrocortisone) and bandaid for one week. If skin feels worse or appears like its spreading, see a doctor. Hope that helps.

You: You need to seek medical care for a number reasons: 1. To make sure you are up to date with your tetanus immunization, and if not, to get an tetanus toxoid injection. 2. To determine if you have infection and to obtain treatment. 3. To make sure you do not have a chemical injury from the cleaning materials.

Popped blister on foot from shoes. Has turned hard and yellowish. Is itchy. Right foot and arm tingling and bit numb. Is this related? Infected?

Popped blister on foot from shoes. Has turned hard and yellowish. Is itchy. Right foot and arm tingling and bit numb. Is this related? Infected?

Blistering: Area turned hard, yellowish, & itchy after popped blister on foot: answer: could be cellulitis.Normally would want to drain blister instead of popping it. As a precaution, take an oral antibiotic such as Keflex or ampicillin. Right foot & arm tingling & bit numb: the arm tingling seems unrelated.

How to treat blisters on ankles from bug bites?

Anti-itch med: If the blisters itch you can use an over the counter cortisone cream or Diphenhydramine on them per directions on tube. If they look slightly red and infected, apply some over the counter antibiotic if not allergic to it. If severely infected, see a doctor (either pcp or podiatrist). Try to not scratch at the bites. You can keep a bandage over them to deter scratching.

My wife just devoled water blisters on her ankle what shoud I do they are the size of a silver dollar?

Possible stasis: Is you wife is older-- she could be at risk for venous stasis- which is incompetent valves in the veins causing blood to pool at the surface of the skin. This causes the blood to break down and ulcerate the skin, causing wounds and venous stasis ulcers. There are a variety of other reasons for wounds in the legs, see your physician for a good history and physical.
