Gram Negative Symptoms?

[ja.child at ukonline.co.uk]

Any lab. with microbiological facilities could do a Gram-stain on a pus swab from one of your pustules.  Recurrent boils don't sound terribly Gram-negative to me, more like a staphylococcal problem (Staphs are Gram-positive.)  It's important that you get proper bacteriological culture and antibiotic sensitivity tests done if you should have a recurrence of these boils.  It dosen't sound much like Lyme either!  
Good luck!
