So, I'm not sure how much your derma explained to you, so I'll start with the basics. Unlike MRSA and Staph, HS lesions are not caused by a bacterial infection. They're a buildup of white blood cells in the apocrine glands. The wonderful lesions we all experience are an inflammatory response to some generally unknown trigger. Granted, the abscesses are extremely prone to becoming infected, they're like a breeding ground waiting to happen. But bacterial infection is not the primary cause. HS is an autoimmune disease.
The antibiotics will help to a certain extent, because most are very powerful anti-inflammatories. Tetracyclines are a favorite of dermatologists for that very reason. The problem, or problems really, are that these medications only work for a limited amount of time. Eventually, within 3-18 months depending on the person, our bodies become acclimated to the drug and every medication in that particular class of antibiotics, is no longer effective. I myself was on Minocyclin for about 6 months before it stopped working.
There are also some pretty severe side effects to being on antibiotics long term. They can wreak havoc on your gastrointestinal system, because they kill all the bacteria in your gut, including the good stuff that helps you digest food and fight off other infections, which is why a lot of doctors recommend a probiotic. And specific antibiotics can be toxic to certain parts of your body if taken long term. Tetracyclines for example are odotoxic, which means they can damage your hearing, permanently. I'm not saying they will, just that they can. If it starts with an 'L' then it'll probably be either Levaquin (Levofloxacin) or Lincomycin. They're both pretty powerful antibiotics, Levaquin is used to treat a lot of skin infections, even plague, and Lincomycin is used to treat Staph.
So if you do go down this road, make sure you talk to your doctor about side effects and what you should look out for, and definitely take a probiotic religiously. If he doesn't explain the risks, get another doctor. Both the antibiotics I mentioned are powerful enough to cause C difficile infection, seizures, etc. I'm not saying you shouldn't take them, because they can offer temporary relief, but you need to get all the information and make a decision that's best for you. The doctor's not the one who has to live with the consequences, you are. It's your body make sure you're the one making the decision.
I would really recommend looking into doing an elimination diet, or an autoimmune protocol. A lot of people, myself included have found that certain foods or food groups trigger breakouts. Nightshades, gluten and nuts tend to be very common triggers for people with HS. I cut out nightshades completely and as long as I avoid them like the plague, I stay in remission. Stress can also trigger breakouts, don't ask me why, but stress generally aggravates every autoimmune disease. HS is no different. I do yoga and I swim a lot, and that really helps. Just make sure you have a way to manage your stress. That'll go a long way as well.
Good luck and ask a lot of questions!!!
