I would suggest you go into the doctor ASAP.

Spiders do not bite you 16 times. A chigger bite might cluster, but 4 or 5 tops.

With MRSA out there today, and the redness you describe, it sounds like
cellutitis to me.

Squeezing is the worst thing you can do... it drives the bacteria deeper into the skin, where more damage can occur.

You might have shingles, but at least what you describe sounds serious to me with the red sunburned look..that is cellulitis. What antibiotic were you given?
If this is MRSA no oral drug will work. If it is shingles, you need Valtrex.

I don't want to alarm you, but I think this is very serious.

Someone with so many dogs may get flea bites, but still fleas prefer the animal to you.

Feeling ill as you are, you cannot separate the ear from the skin lesions. Don't let this get away from you.
Cover the weeping area with a bandaid --after cleaning with hydrogen peroxide. Put some triple antibiotic on
the weeping lesion and then the bandaid.
