What is Blister?

A blister is a small pocket of fluid within the upper layers of the skin, typically caused by forceful rubbing (friction), burning, freezing, chemical exposure or infection. Most blisters are filled with a clear fluid (serum or plasma) and some times filled with pus (if they become infected) or blood.

As per your complain it seems that a blister over the tongue can be a canker sore while pus filled lump under the chin can be due to bacterial infection and as it has already crusted you need not to worry about it again..

I have had a rash / blisters on my body for weeks. I 've also just complete two rounds of shingles. I am a non-hodgkins survivor as well. I have also previously (last Spring) big problems producing white blood cells, buy my oncologist's stated that the white count was 7-2. My eosinofils were high.
these blisters show up on all parts of my body.
Thanks for the query,

These blisters can be shingles itself.

As you mentioned you are a non hodgkin survivor and your EBC is low,

There is high chance that zoster gets dissaminated.

Please meet a dermatologist for final diagnosis and treatment

Let me know if you have any other doubt.
