water blisters

[mari287]

My father is currently in a nursing facility because he has Alzheimer's disease. A few weeks ago he woke up with large water blisters on his arm. We were told by his doctor that they were caused by burns. He was given an antibiotic ointment and the blisters were drained. They subsided after about 2 weeks. This morning my dad woke up with the same blisters on his arm again. He doesn't go outside so it can't be poison ivy or oak. But this can't be another burn. Does anyone have any idea what this could be?? Please help with any advice. It's greatly appreciated.
Thank you

Hi,

Most of the times such watery boils are caused by anerobes such as clostridium species. He should see a surgeon and the pus sample must be sent for culture and sensitivity. I suggest he gets admitted and undergoes routine blood test for the same as it might lead to sepsis if not treated by an appropriate antibiotic.

Hello,
These water blisters do not look like burns, but for these water blisters the possibilities of bacterial staph infection and any contact dermatitis, allergic reaction causing blisters should be ruled out. I suggest you to get an evaluation done from a dermatologist and get it evaluated. The fluid from the blisters can be sent for histopath examination.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
