I have been getting frequent mrsa infections many times i am unable to keep down antibiotics but also i don't think my pcp understands mrsa anyway i am worried have been getting more and more of these tiny dot cherry red dots is this sepsis?

Unlikely. MRSA accounts for more than half of common pustules, abscesses & minor folliculitis seen in the office. It moves side to side locally and rarely gets bloodborne to cause sepsis unless introduced during surgery or in an immune impaired person. Try triple antibiotic cream to your nasal outlets 2Xd and a bath with 2 cups of bleach/20 G water during treatment.
