Recurrent vulval boils - painful and almost constant

About me: Age: 28 Sex: Female Medical history: Chronic migraine, recurrent UTI, hypermobility spectrum disorder, eczema, piriformis sydrome & pelvic floor dysfunction. Medications: Galcenzumab (Emgality injection), Candesartan, pizotifen, methanamine Hippurate, desogestrel Supplements: D-mannose, magnesium glycinate, coQ10, riboflavin, cod liver oil, multivitamin with iron, vitamin D and folic acid Weight: 78kg Height: 164cm BMI: 29 duration of issue: 2+ years A few years back I started developing painful boils on my vulval skin. They occur both on the labia Majora (area with hair) and labia minora/between the labia (area without hair) and typically occur 1-2 at a time, starting as an itchy spot, growing into a red tender lump over 2-3 days, persisting for a further 2-3 days before bursting and discharging pus and healing in around 2-5 days after they burst. So all in they stick around for just under 2 weeks from start to finish. Previously I would get one every 3-4 months, but recently I have been getting them back to back, often with no boil free time between lesions, and it is really affecting me as it is both very painful, but also massively interfering with my sex life as I cannot be intimate with these boils given they are contagious. I sometimes have similar boils in my hairline at the back of my neck, but these are less common and also much less painful. 2 years ago I saw my GP and they prescribed 3 months of lymecycline which got rid of the infections for the 3 months, but they came back quickly afterwards. I have then tried a decolonisation with chlorhexidine wash about 1 year ago, and that helped for about 3-4 months before they slowly started occurring again, the duration between them getting shorter each time up until now when they are basically back to back again. I normally shower with chlorhexidine on the vulval area every other day to prevent them, but it's not really working. I do not shave the area at all and only trim the hairs. I live with my husband and 2 cats. Interestingly my husband does get similar spots/boils around his hips/buttocks at times, and when we used the chlorhexidine wash they go away. At the moment he has some but not many. I also work in healthcare and have a mother who I occasionally care for who is a known carrier if some fairly resistance carbapenem and methicillin bacteria strains so I think I have likely picked up this issue from work or from close contact with my mother. So far I am losing weight & also being dilligent with hygiene, but I just can't get on top of this. My questions are: \- Does this definitely sound like recurrent Staph A or could it be something else like hidradenitis? \- Do I need any specific tests like bloods or swabs which may help in this case? \- How would you recommended managing this issue? A further eradication regime for both me and my husband (chlorhexidine but this time add the nasal cream too) or another treatment? \- What is the best way to eradicate staph from my home? I'm worried I have contaminated my home and it's going to be very easy to reinfect myself in the future. thanks in advance.
