Darn Kimberley! 4 times this year! 

 Your poor hubby. Staph just SUCKS. I had it a few years ago on the side of my calf...OMG - it got as huge as a baseball! 

 I too thought it was a spider bite and actually let it go for a long time because I thought that's all it was. ALOT of people here had it around that time...it was just crazy! The hospital said that they had never seen such a bad outbreak of so many staph infections! Thank goodness I went in when I did, they said that if I would have waited any longer, I would of gotten blood poisioning 

 By the time I went in to the ER, it was hurting me SO BAD that I could barely even walk!  
Be sure and tell your hubby to wash it every single day with Hibiclens (if he isn't already) which I'm sure if this is his 4th time for him to have it this year, you guys already know about this! 
Hope he gets rid of it soon!
