What can I do for the painful red blisters filled with water all over my lower back from cellulitis?

What can I do for the painful red blisters filled with water all over my lower back from cellulitis?

Depends on cause: If the blisters don't cross the midline, consider shingles (tx: acyclovir). With cellulitis present, if the area of blistering is also very edematous (swollen), then mobilization of fluid from this area (e.g. Diuresis) can also help, along with abx. If the pt looks ill, has a fever, and the blisters are looking more violaceous, then go to the ed- the infection may be getting worse. ...Read more

A bites that was red and swollen now is a blister like bubble hard filled with clear liquid, what bit me?

Regardless of what: With injury to our skin, inflammation occurs which means the area becomes red, warm, tender and with swelling. Swelling occurs under the skin layers and causes them to bulge creating a protective fluid cushion called a blister. As the area heals, the fluid will be resorbed or when no longer needed, the blister opens and it drains. This should take about a week. Keep it covered and protected. ...Read more

What could be the cause of blisters on the inner sides of my feet. They are usually filled with a clear liquid and sometimes itch.

Acute athlete's foot: The first thing that comes to mind is that this is one of the presentations of acute athlete's foot. Use drying soaks (epsom salts or dilute vinegar) and a topical antifungal... I prefer patients use lotrimin ultra or Lamisil (terbinafine) cream. You can use certain-dry pads or solutions to decrease perspiration. If this doesn't work, see a podiatrist and be sure to inform them of what you have tried already. ...Read more

Maybe herpes: Sounds like onset of herpes simplex infection. You'll know in a day or so--lesions will probably hurt more and itch less. If they stay itchy, possible fungal infection.

For herpes, BHT (available on line or health food store) 2, 000 mg per day (taken in divided doses). Lesions should clear up in a day or two. Another "home remedy" is to apply DMSO ("horse liniment") from a veterinary supply. ...Read more
